Paolo "Nusco" Perrotta resolved ANN-612.
----------------------------------------

    Resolution: Fixed

Should be OK now. Thanks Aleksei.

Emmanuel, I'm still having some trouble running the tests under OS X. I did run the tests in commons-annotations, but I have failing tests all over the place in validator, entitymanager etc. Could you please check that this patch didn't break anything there?

> The following property makes no problem:
> 	private J<Object> f;
> 	@Transient
> 	public J<Object> getF() {
> 		return f;
> 	}
> 	public void setF(J<Object> f) {
> 		this.f = f;
> 	}
> So I believe it's the arrayd type which is problematic.
> From the stack trace, I believe the problem is with hibernate-commons-annotations.
> I also attach the class that reproduces the problem.
