JDK-6594219 - Plugin loads Swing classes
Description
###@###.### pointed out that the new Java Plug-In was still loading some Swing classes like javax.swing.JFrame in support of the ConsoleWindow, even if the Java Control Panel setting was to not show the Java Console. It was stated that the old Java Plug-In did not exhibit this behavior.

EVALUATION Investigation with ###@###.### showed that because the return type of the method sun.plugin.JavaRunTime.getJavaConsole() was ConsoleWindow, simply loading the JavaRunTime class was forcing ConsoleWindow and all of its superclasses to be loaded. This must have been true of the old plug-in as well, only because the old plug-in's tracing code was initialized later than in the new plug-in it was not apparent. Changing this method to return Object and doing explicit casts at the call sites solves the problem.
