Fix: JsonJacksonCodec fails to serialize Throwable on Java17

[tomj-vm]

This fixes issue: #5369

The serialization of Throwable instances would fail on Java17 with error:

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Invalid type definition for type `java.lang.Throwable`: Failed to call `setAccess()` on Field 'detailMessage' (of class `java.lang.Throwable`) due to `java.lang.reflect.InaccessibleObjectException`, problem: Unable to make field private java.lang.String java.lang.Throwable.detailMessage accessible: module java.base does not "opens java.lang" to unnamed module @32eff876
  //...
