/***
 * This exception is thrown in local mode when we don't want to kill the jvm.
 * 
 * Why? The only way to kill an operation in prod is to throw an exception up 
 * to storm.  That presents problems in local mode, because the storm will
 * kill the entire process.  Because we sometimes want to test that errors
 * are being handled, we instead throw this exception.  This exception 
 * is caught at all key places in GMB and simply waits before continuing
 * on with the loop.  That is, the JVM should never die when this is thrown
