* Add Troubleshooting Guide entry for custom adapter being unused
* Extend documentation
* Fix line endings
* Mention missing adapter in case of "Expected BEGIN_OBJECT ..." exception
* Fix `GsonBuilder.setDateFormat` ignoring partial DEFAULT; deprecate `setDateFormat(int)`
* Remove date format methods not used by main code
* Adjust example
* Enable additional Error Prone checks & fix violations
Some of them also enforce additional Google Java Format requirements which
are not handled by google-java-format, such as disallowing wildcard imports.
Not all experimental checks have been listed because some are not applicable,
such as Dependency Injection framework checks, or checks related to Guava's
immutable collections (since Gson's main code does not have a dependency on
Guava).
Other checks have been omitted because they are probably not relevant
(this was a subjective choice), or would require larger refactoring or
would flag issues with the public API, which cannot be changed easily.
* Address review feedback

* Perform minor code clean-up
Notable changes:
- Replace most usages of `<code>` with `{@code ...}` in Javadoc
- Add proper summary sentence to `GsonBuilder.enableComplexMapKeySerialization`
- Extend documentation for `GsonBuilder.setDateFormat` methods
- Fix `TypeToken.isAssignableFrom(Type)` throwing AssertionError in some cases
Maybe the method should not throw an exception in the first place, but it
might not matter much since it is deprecated already anyway.
- Remove outdated `throws NumberFormatException` from internal
`JsonReader.nextQuotedValue`; the behavior had been changed by
85ebaf7c35
- Fix incorrect documentation on JsonScope fields
- Fix unit tests having 'expected' and 'actual' switched
- Use dedicated Truth methods instead of `isTrue()` / `isFalse()`
- Use common helper methods in JsonWriterTest to avoid duplication
* Implement `toString()` for ReflectionAccessFilter constants
* Address most of the review comments
* Add comment about `source.scm.tag=HEAD` warning
Actually it looks like the warning is not actually caused by usage of
`HEAD` as value, but rather because the project has a snapshot version
during development (which is expected though), see
https://github.com/apache/maven-artifact-plugin/blob/maven-artifact-plugin-3.5.0/src/main/java/org/apache/maven/plugins/artifact/buildinfo/BuildInfoWriter.java#L140
But this is not a problem either since during release a non-snapshot
version is used.
`DateFormat` validates these arguments as well, but it is currently not
documented, see https://bugs.openjdk.org/browse/JDK-8319628.
Also moves the other tests for `setDateFormat(String)` from
DefaultTypeAdaptersTest to GsonBuilderTest.
* validating the date format, add test case, since NumberFormatException extends IllegalArgumentException, it is only necessary to write IllegalArgumentException.
* Apply code formatting with Spotless

* Support non-generic type for `TypeToken.getParameterized` for legacy reasons (#2447)
This partially restores the behavior before a589ef2008,
except that back then for a non-generic type a bogus `TypeToken(ParameterizedType)`
was created, whereas now a `TypeToken(Class)` is created instead.
* Fixed Typo in GsonBuilder.java (#2449)
* Make date-formatting tests less fragile with regular expressions. (#2450)
* Make date-formatting tests less fragile with regular expressions.
This is not great. We should really ensure that formatted dates are the same
regardless of JDK version. There is code that attempts to do that but it is not
really effective. So for now we fudge around the differences by using regular
expressions to paper over the differences.
* Temporarily add test-debugging code.
* Another attempt at debugging a test failure.
* Fix pattern in assertion.
* Modification in test cases (#2454)
* Fixed Typo in GsonBuilder.java

This annotation indicates that return value of the annotated method does
not need to be used. If it is _not_ present on a non-void method, and if
Error Prone's `CheckReturnValue` is active, then calling the method
without using the result is an error. However, we are not enabling
`CheckReturnValue` by default here.
Also update some code that does ignore return values, so that the
returned value is used, if only by assigning it to an unused variable.

* Build on JDK 8 and 17 as well as 11.
* Remove JDK 8 for now.
`DefaultDateTypeAdapterTest` fails.
* Tweak javadoc to avoid warnings.
Mostly these are about using `<h3>` when the previous tag was `<h1>`,
and the like. This previous tag might be implicit (part of what javadoc
itself outputs rather than the HTML in doc comments).
Apparently JDK 11 puts method javadoc inside `<h2>` while JDK 11 puts it
inside `<h3>`. Or something like that. Anyway it doesn't appear to be
possible to use `<h3>` _or_ `<h4>` and please both.
* 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
* 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.
