If an application is run with JVM argument "-Dcom.sun.management.jmxremote"
and sets a custom class loader as the context class loader explicitly in the
main application thread, AWT event dispatching thread (EDT) will not inherit
its context class loader from the application main thread on JDK 6u51 and
later releases of JDK 6. This behavior causes problems for applications
relying on EDT having its context class loader inherited from the application
main thread.
