HDC调试需求开发（15万预算）,能者速来！>>>
使用Jemeter做压测启动500个线程 执行10分钟之后然后停掉Jemeter 我在把Tomcat停掉就会报

ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2
JDWP exit error AGENT_ERROR_NO_JNI_ENV(183): [util.c:838]
开始我以为Caused by: java.lang.ClassNotFoundException: ch.qos.logback.core.status.WarnStatus不存在但是这个类其实是存在的 我要是启动tomcat 不做压测正常关闭就没问题，请问这是什么问题
