   Just to avoid any doubt, we tried below too. We see the lines printed directly to System.out and System.err were missing too.
   
   ```
   	public static JsonObject main(JsonObject args) {
       	JsonObject resp = null;
       	try {
       		logger.info("Enter WhiskMain");
       		logger.info(getCallInfo());
       		
       		//temporary workaround to prevent JVM heap size is go beyond 
       		//the container limit of openwhisk. the issue can be tracked at
       		//https://github.com/apache/incubator-openwhisk/issues/2389
       		System.gc();
       		
       		resp = executeImpl(args);
       		return resp;
       	} catch (RuntimeException | Error e) {
       		logger.error("WhiskMain caught unchecked throwable", e);
       		throw e;
   	} finally {
   		System.out.println("Printed by System.out - before last log item");
   		System.err.println("Printed by System.err - before last log item");
       		logger.info("Exit WhiskMain, resp=" + resp);
   		System.out.println("Printed by System.out - after last log item");
   		System.err.println("Printed by System.err - after last log item");
   		System.out.flush();
   		System.err.flush();
   	}
       }
   ```
