JMeter閃退

JMeter在啓動的時候閃退 ，而後在jmeter.bat的最後加了pause，再啓動時，報錯： java.lang.InstantiationError: org.apache.log.Logger at org.apache.log.Hierarchy.(Hierarchy.java:73) at org.apache.log.Hierarchy.(Hierarchy.java:39) at org.apache.jorphan.logging.LoggingManager.getLoggerForClass(LoggingManager.java:243) at org.apache.jmeter.JMeter.(JMeter.java:106) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at java.lang.Class.newInstance(Unknown Source) at org.apache.jmeter.NewDriver.main(NewDriver.java:243) JMeter home directory was detected as: D:\apache-jmeter-4.0 請按任意鍵繼續. . . 爲毛？？？
