* Add integration test for GraalVM Native Image * Enable 'quickBuild' mode Seems to improve build speed, and at least for the previous issue with `RecordComponent` still causes test failures (as expected) if the fix is reverted.

graal-native-image-test
This Maven module contains integration tests for using Gson in a GraalVM Native Image.
Execution requires using GraalVM as JDK, and can be quite resource intensive. Native Image tests are therefore not enabled by default and the tests are only executed as regular unit tests. To run Native Image tests, make sure your PATH and JAVA_HOME environment variables point to GraalVM and then run:
mvn clean test --activate-profiles native-image-test
Technically it would also be possible to directly configure Native Image test execution for the gson module instead of having this separate Maven module. However, maintaining the reflection metadata for the unit tests would be quite cumbersome and would hinder future changes to the gson unit tests because many of them just happen to use reflection, without all of them being relevant for Native Image testing.
Reflection metadata
Native Image creation requires configuring which class members are accessed using reflection, see the GraalVM documentation.
The file reflect-config.json contains this reflection metadata.
You can also run with -Dagent=true to let the Maven plugin automatically generate a metadata file, see the plugin documentation.
