我整合椒与我的Tomcat（Tomcat的7.0.53，JDK 1.8.0_45）椒防止Tomcat关闭
我配置在Tomcat的目录/ bin中/ setenv.sh的javaagent：
CATALINA_OPTS="$CATALINA_OPTS -javaagent:/path/to/jolokia-jvm-1.2.0-agent.jar=config=/path/to/config.properties"
现在，我有麻烦关闭tomcat。 ps显示我，那个java进程已经在运行。 这里北京时间关机的输出：
-bash-4.1$ ./shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat/7.0.53/instance/ingest-news
Using CATALINA_HOME: /usr/local/tomcat/7.0.53/instance/ingest-news
Using CATALINA_TMPDIR: /usr/local/tomcat/7.0.53/instance/ingest-news/temp
Using JRE_HOME: /usr/local/java64/jdk1.8.0_45
Using CLASSPATH: /usr/local/tomcat/7.0.53/instance/ingest-news/bin/bootstrap.jar:/usr/local/tomcat/7.0.53/instance/ingest-news/bin/tomcat-juli.jar
Using CATALINA_PID: /var/run/tomcat/ingestnews.pid
Tomcat did not stop in time. PID file was not removed. To aid diagnostics a thread dump has been written to standard out.
这是线程转储：

现在当我删除CATALINA_OPTS的javaagent，一切又行之有效。我已经搜索了stackoverflow，但没有找到任何解决方案。
