I'm curious on how it can work with JComboBox then... ?
In Java all threads share a single address space. So although you can have a world of concurrency problems when writing threaded programs in Java, it's still perfectly possible to create complex objects in one thread and access them in another thread. And the AWT/Swing classes are largely thread-safe (for reading-type things anyway).
