Not sure that it is a bug - just to confirm: looks like part of exception in java stacktrace is erased - I see only last lines + some strange
Exception in thread “main” java.lang.reflect.InvocationTargetException
at sun.reflect.NativeMethodAccessorImpl.invoke0 on line 0
at sun.reflect.NativeMethodAccessorImpl.invoke on line 62

Is it done intentionally?
