Generic attribute produces to not-compilable Java code

[arnobl]

For instance (commited in k3.test, TestGenerics):

@Aspect(className=typeof(Object)) abstract class TestGenericsAttrGeneric<T> { protected var T attr = null }

produces the following Java code that does not compile:

protected static ? privattr(final Object _self) { return test.TestGenericsAttrGeneric.self.attr; }
