/**
 * 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.)
