Gson 2.14.0

What's Changed

• Add type adapters for java.time classes by @​eamonnmcmanus in google/gson#2948

  When the java.time API is available, Gson automatically can read and write instances of classes like Instant and Duration. The format it uses essentially freezes the JSON representation that ReflectiveTypeAdapterFactory established by default, based on the private fields of java.time classes. That's not a great representation, but it is understandable. Changing it to anything else would break compatibility with systems that are expecting the current format.

  With this change, Gson no longer tries to access private fields of these classes using reflection. So it is no longer necessary to run with --add-opens for these classes on recent JDKs.

• Remove com.google.gson.graph by @​eamonnmcmanus in google/gson#2990.

  This package was not part of any released artifact and depended on Gson internals in potentially problematic ways.

• Validate that strings being parsed as integers consist of ASCII characters by @​eamonnmcmanus in google/gson#2995

  Previously, strings could contain non-ASCII Unicode digits and still be parsed as integers. That's inconsistent with how JSON numbers are treated.

• Fix duplicate key detection when first value is null by @​andrewstellman in google/gson#3006

  This could potentially break code that was relying on the incorrect behaviour. For example, this JSON string was previously accepted but will no longer be: {"foo": null, "foo": bar}.

• Remove Serializable from internal Type implementation classes. by @​eamonnmcmanus in google/gson#3011

  The nested classes ParameterizedTypeImpl, GenericArrayTypeImpl, and WildcardTypeImpl in GsonTypes are implementations of the corresponding types (without Impl) in java.lang.reflect. For some reason, they were serializable, even though the java.lang.reflect implementations are not. Having unnecessarily serializable classes could conceivably have been a security problem if they were part of a larger exploit using serialization. (We do not consider this a likely scenario and do not suggest that you need to update Gson just to get this change.)

• Add LegacyProtoTypeAdapterFactory. by @​eamonnmcmanus in google/gson#3014

  This is not part of any released artifact, but may be of use when trying to fix code that is currently accessing the internals of protobuf classes via reflection.

• Make AppendableWriter do flush and close if delegation object supports by @​MukjepScarlet in google/gson#2925

Other less visible changes

• Add default capacity to EnumTypeAdapter maps by @​MukjepScarlet in google/gson#2959
• refactor: move derived adapters from Gson to TypeAdapters by @​MukjepScarlet in google/gson#2951
• Optimize new Gson() by @​MukjepScarlet in google/gson#2864
