+/**
+ * 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.terminal.gwt.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.
