package p;

public class J {

	public void foo(Object a) {
		final J j;
		if(a instanceof J) {
			j = (J) a;
		} else {
			j = new J();
		}
	}
}

Invoke "Join variable declaration" changes semantics as it casts a without the instanceof check and introduces another compile warning as the else branch tries to reassign a final var.
Not sure about a nice solution at the moment.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
