+/**\r
+ * A wrapper for the GWT 1.6 compiler that runs the compiler in a new thread.\r
+ * \r
+ * This allows circumventing a J2SE 5.0 bug (6316197) that prevents setting the\r
+ * stack size for the main thread. Thus, larger widgetsets can be compiled.\r
+ * \r
+ * This class takes the same command line arguments as the\r
+ * com.google.gwt.dev.Compiler class.\r
+ * \r
+ * A typical invocation would use e.g. the following arguments\r
+ * \r
+ * "-workDir WebContent/ITMILL/widgetsets com.itmill.toolkit.terminal.gwt.DefaultWidgetSet"\r
+ * \r
+ * In addition, larger memory usage settings for the VM should be used, e.g.\r
+ * \r
+ * "-Xms256M -Xmx512M -Xss8M"\r
+ * \r
+ * The source directory containing widgetset and related classes must be\r
+ * included in the classpath, as well as the gwt-dev-[platform].jar and other\r
+ * relevant JARs.\r
