'"JavaBridge.jar" SERVLET:8080'); self::$configedFlag = true; } var_dump(self::$configedFlag); } } JavaBridgeLoader::preconfig(); ?> I expect for the result is "bool(false) bool(true) at the first time, And then: bool(true) bool(true) at the second time" I am not a phper, I am a java liker and want to learn the php lanugage, I dont know why it can not performence like java performence, So I report this bug!
