IllegalArgumentException on vararg methods

[balazsbalazs]

Sample class:

public class ClassA {
  public void foo(String ...args) {
  }
}

Code generated by boundbox:

public void foo(String[] arg0) {
  try {
    Method methodToInvoke = ClassA.class.getDeclaredMethod("foo", String[].class);
    methodToInvoke.setAccessible(true);
    methodToInvoke.invoke(object, arg0);
  }
...

When invoked this results in an IllegalArgumentException.

The correct code would be either:

methodToInvoke.invoke(object, (Object)arg0);

or

methodToInvoke.invoke(object, new Object[] {arg0});

I'm going to look into the code and try to submit a pull request (I wanted to look into compile time annotations anyway, so it's a good exercise anyway).

Thx very much. I got no time to enhance BoundBox before Xmas. If you find a workaround, and add tests for it, a pull request would be accepted cheerfully.

I'll try but as usual I got a hundred other things before this :) It's on my todo list though.
