I think he means something like:

public void finalize(){
synchronized(QTSession.terminationLock())
{
super.finalize();
}
}

in all your classes that have a QTJava class as an ancestor

looks strange to me though, you may have instantiated QTJava classes directly (which you haven't extended with a subclass to fix finalize there)

plus this may be block the garbage collector, depending on what is "QTSession.terminationLock()", not sure what this function is supposed to return (maybe just a dummy object used globally in QT as a lock when doing termination stuff)

Better solution would be to patch "QTObject" (or wasn't there such a common ancestor in QTJava - it's been some months since I last played with QTJ). Maybe Java1.3 or 1.4 allows you to change a class method implementation at runtime (or something similar). Else you could patch that class in QTJava.zip using JAD (but it's deployed by Apple, not you, so it's not an option)
