I guess that the uninstall() above is called when the L&F was basic(since
BasicPopupMenuUI is used) and then changed for some reason, so when the method
in the BasicPopupMenuUI.java will be called we will find that the current L&F
is different and call "uninstall()", so this is my question: will the leak will
exist in that case? I mean the code changed by the current fix will not be
executed since we will exit after "uninstall()".
