The Java installer for the source code for Mustang is executing UI code on a non-UI thread. This can cause deadlocks on some systems.

The stack trace below shows that the installer com.sun.tools.extractor.Installer calls the method doit which calls "showDialog" from the main thread. This code should be executed on the EDT via the use of SwingUtilities.invokeLater().
