FST doesn't work with GraalVM native-image

[hamzajg]

Hello everyone.

Try to create a native image using GraalVM version 21.1.0 with Java 11. But when running the native image, the following exception is always thrown:

Exception in thread "main" com.oracle.svm.core.jdk.UnsupportedFeatureError: SerializationConstructorAccessor class not found for declaringClass: [Ljava.lang.Object; (targetConstructorClass: java.lang.Object). Usually adding [Ljava.lang.Object; to serialization-config.json fixes the problem.

Thanks..

Hallo, @hamzajg has a workaround for this problem, but it's far from ideal. We disallow serialization of Object[] and byte[]. It would be great to support all Java types and arrays.

We are happy to contribute the GraalVM implementation details so you can support it.
