/**
* A wrapper for the GWT 1.6 compiler that runs the compiler in a new thread.
*
* This allows circumventing a J2SE 5.0 bug (6316197) that prevents setting the
* stack size for the main thread. Thus, larger widgetsets can be compiled.
*
* This class takes the same command line arguments as the
* com.google.gwt.dev.GWTCompiler class. The old and deprecated compiler is used
* for compatibility with GWT 1.5.
*
* A typical invocation would use e.g. the following arguments
*
* "-out WebContent/VAADIN/widgetsets com.vaadin.DefaultWidgetSet"
*
* In addition, larger memory usage settings for the VM should be used, e.g.
*
* "-Xms256M -Xmx512M -Xss8M"
*
* The source directory containing widgetset and related classes must be
* included in the classpath, as well as the gwt-dev-[platform].jar and other
* relevant JARs.
*
* @deprecated with Java 6, can use com.google.gwt.dev.Compiler directly (also
* in Eclipse plug-in etc.)
