Fixesgoogle/gson#1794
Added support in the ReflectionHelper to detect if a class is a record
on the JVM (via reflection), and if so, we will create a special
RecordAdapter to deserialize records, using the canoncial constructor.
The ReflectionTypeAdapterFactory had to be refactored a bit to support
this. The Adapter class inside the factory is now abstract, with
concrete implementations for normal field reflection and for Records.
The common code is in the Adapter, with each implementation
deserializing values into an intermediary object.
For the FieldReflectionAdapter, the intermediary is actually the final
result, and field access is used to write to fields as before. For the
RecordAdapter the intermediary is the Object[] to pass to the Record
constructor.
* Fixed comments from @Marcono1234
Also updated so that we now use the record accessor method to read out
values from a record, so that direct field access is not necessary.
Also added some tests, that should only execute on Java versions with
record support, and be ignored for other JVMs
* Fixed additional comments from @Marcono1234
* Made Adapter in ReflectiveTypeAdapterFactory public
Fix comment from @eamonnmcmanus
* Fix TypeAdapterRuntimeTypeWrapper not detecting reflective TreeTypeAdapter
Previously on serialization TypeAdapterRuntimeTypeWrapper preferred a
TreeTypeAdapter without `serializer` which falls back to the reflective
adapter. This behavior was incorrect because it caused the reflective
adapter for a Base class to be used for serialization (indirectly as
TreeTypeAdapter delegate) instead of using the reflective adapter for
a Subclass extending Base.
* Address review feedback
* Convert TypeAdapterRuntimeTypeWrapperTest to JUnit 4 test
* Prefer wrapped reflective adapter for serialization of subclass
* Detect reflective adapter used as delegate for Gson.FutureTypeAdapter
* Tiny style tweak.

* Fix JsonReader.skipValue() not behaving properly at end of document
JsonReader implementation erroneously reset `peeked` to PEEKED_NONE;
JsonTreeReader threw ArrayIndexOutOfBoundsException.
* Fix JsonReader.skipValue() not behaving properly at end of array and object
For JsonReader this caused an IllegalStateException (in the past it caused
JsonReader to get stuck in an infinite loop); for JsonTreeReader it only
popped the empty iterator but not the JsonArray or JsonObject, which caused
peek() to again report END_ARRAY or END_OBJECT.
* Only have JsonReader.skipValue() overwrite path name when name was skipped
This improves the JSON path when the value for a property was skipped and
before the subsequent property (or the end of the object) getPath() is called.
* Address feedback; improve test coverage

* Perform numeric conversion for primitive numeric type adapters
This should probably not be visible to the user unless they use the
non-typesafe `Gson.toJson(Object, Type)` where unrelated number types can
be used, or when malformed generic containers are used. For example a
`List<Byte>` containing a Float.
This change also has the advantage of avoiding `JsonWriter.value(Number)`
for primitive type adapters. That method has some overhead because it needs
to make sure that the value is a valid JSON number. However, for primitive
numbers this check is redundant.
* Don't call `JsonWriter.value(float)` for backward compatibility
* Fix typo in comments
The JsonSerializer/Deserializer adapters used to ignore this attribute
which result in inconsistent behaviour for annotated adapters.
Fixes#1553

* Make Object and JsonElement deserialization iterative
Often when Object and JsonElement are deserialized the format of the JSON
data is unknown and it might come from an untrusted source. To avoid a
StackOverflowError from maliciously crafted JSON, deserialize Object and
JsonElement iteratively instead of recursively.
Concept based on 51fd2faab7
But implementation is not based on it.
* Improve imports grouping
* Address review feedback
Follow-up to comments on #2130, which introduced a new override which was not overridden by `JsonTreeWriter`. Also tweaks the doccomments for `float`, `double` and `Number` variants of `JsonWriter.value`.
Supplement to the fix for #1127.
* Add comments regarding multiple bounds of wildcard
* Remove WildcardType check in getCollectionElementType
The returned Type is never a wildcard due to the changes made to getSupertype
by commit b1fb9ca9a1.
* Remove redundant getRawType call from MapTypeAdapterFactory
getRawType(TypeToken.getType()) is the same as calling TypeToken.getRawType().
* Make TypeToken members private
* Remove incorrect statement about TypeToken wildcards
It is possible to use wildcards as part of the type argument, e.g.:
`new TypeToken<List<? extends CharSequence>>() {}`
* Only allow direct subclasses of TypeToken
Previously subclasses of subclasses (...) of TypeToken were allowed which
can behave incorrectly when retrieving the type argument, e.g.:
class SubTypeToken<T> extends TypeToken<Integer> {}
new SubTypeToken<String>() {}.getType()
This returned `String` despite the class extending TypeToken<Integer>.
* Throw exception when TypeToken captures type variable
Due to type erasure the runtime type argument for a type variable is not
available. Therefore there is no point in capturing a type variable and it
might even give a false sense of type-safety.
* Make $Gson$Types members private
* Rename $Gson$Types.getGenericSupertype parameter
Rename the method parameter to match the documentation of the method and
to be similar to getSupertype(...).
* Improve tests and handle raw TypeToken supertype better
* Make some $Gson$Types members package-private again to prevent synthetic accessors
* Remove TypeToken check for type variable
As mentioned in review comments, there are cases during serialization where
usage of the type variable is not so problematic (but still not ideal).
* Add support for reflection access filter
* Improve documentation
* Fix compilation errors
* Relax handling for BLOCK_ALL when invoking default constructor
* Improve handling for inherited fields
* Fix accessible test failing for static fields
* Simplify ReflectiveTypeAdapterFactory field writing
* Fix GsonBuilder changes affecting created Gson instances
* Improve documentation
* Improve handling for IllegalAccessException
For Java < 9, AccessibleObject.canAccess is not available and therefore checks
might pass even if object is not accessible, causing IllegalAccessException
later.
* Fix incorrect GsonBuilder.addReflectionAccessFilter documentation
* Added parsing support for enum that has overridden toString() method.
* Fix a tiny formatting problem
* Fixed formatting issue

* Remove UnsafeReflectionAccessor
Revert #1218
Usage of sun.misc.Unsafe to change internal AccessibleObject.override field
to suppress JPMS warnings goes against the intentions of the JPMS and does not
work anymore in newer versions, see #1540.
Therefore remove it and instead create a descriptive exception when making a
member accessible fails. If necessary users can also still use `java` command
line flags to open external modules.
* Fix failing to serialize Collection or Map with inaccessible constructor
Also remove tests which rely on Java implementation details.
* Don't keep reference to access exception of ConstructorConstructor
This also avoids a confusing stack trace, since the previously caught
exception might have had a complete unrelated stack trace.
* Remove Maven toolchain requirement
* Address review feedback
* Add back test for Security Manager
* Improve TreeTypeAdapter thread-safety
Gson claims to be thread-safe so TreeTypeAdapter.delegate() might be
called by multiple threads. To guarantee that each thread sees a fully
constructed `delegate`, the field has to be `volatile`.
* Improve TreeTypeAdapter thread race comment
There are situations where the stack of JsonTreeReader contains a JsonArray
or JsonObject without a subsequent Iterator, for example after calling peek()
or nextName().
When JsonTreeReader.getPath() is called afterwards it therefore must not
assume that a JsonArray or JsonObject is always followed by an Iterator.
The only reason why this never caused an ArrayIndexOutOfBoundsException in
the past is because the stack has an even default size (32) so it would just
have read the next `null`.
However, if the stack had for example the default size 31, a user created a
JsonTreeReader for 16 JSON arrays nested inside each other, then called 15
times beginArray(), followed by peek() and getPath() the exception would
occur.
* Object and Number type adapters number deserialization can be configured
* Change wording of ToNumberStrategy documentation
* Use inline links in doc sparingly
If the element has already been linked before, don't create a link for
every subsequent occurrence.
See also (slightly dated)
https://www.oracle.com/technical-resources/articles/java/javadoc-tool.html#inlinelinks
* Link to default to-number policies in ToNumberStrategy doc
* Reduce code duplication for deserializing Number
* Hide default factory constants of NumberTypeAdapter and ObjectTypeAdapter
This encapsulates the logic a little bit better.
Additionally refactored factory created by NumberTypeAdapter to only create
TypeAdapter once and then have factory reuse that adapter for better
performance.

When enum value was obfuscated by proguard, EnumTypeAdapter raise NoSuchFieldException even if apply SerializedName annotation.
Because EnumTypeAdapter cannot find obfuscated enum constant field with its name.
