Posting signals to javahelper process

You can post signals to a Java application. In NSJ, if parallel and CMS GC (deprecated in NSJ 11) is enabled, javahelper processes are created to perform the garbage collection. The javahelper process installs signal handlers for the synchronous signals and blocks the asynchronous signals. Hence, posting asynchronous signals to javahelper process does not have any effect. When a synchronous signal occurs, the javahelper process signal handler creates a error log file and terminates.
