i read some code and i know the reason my JAVA_HOME is my jdk home so the dir JAVA_HOME/lib/ext does not exist it locate in JAVA_HOME/jre/lib/ext so i mod JAVA_HOME to jre path and it pass

Sorry for the late response. I am a little busy these days. But I will return to this project when I get some free time.
