What is a "native array variable"? What happens? What do you expect?

hi @matthiasblaesing

I believe that problem is in this line:

https://github.com/apache/netbeans/blob/03aa32d15aba53f980e095b1a8efa6700c515331/java/debugger.jpda/src/org/netbeans/modules/debugger/jpda/expr/EvaluatorVisitor.java#L443

Any method could be called in a native array reference.... but I believe that some methods may be enabled, like: toString, equals, hashcode and clone right?

@dyorgio you need to provide steps to reproduce. That includes necessary sample source. At this point I have zero idea what you are talking about.

Sorry, sometimes it is clear in your mind, but not outside 😝

That makes more sense. Thank you
