* 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- Remove outdated `throws NumberFormatException` from internal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.
* 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
