I am seeing these warnings in catalina.out while stopping the tomcat. Why these errors appearing? Are these harmful? Is simplewebapp actually leaking memory by not stopping threads? Thanks in Advance.
WARNING [localhost-startStop-2] org.apache.catalina.loader. WebappClassLoaderBase.clearReferencesThreads The web application [simplewebapp] appears to have started a thread named [pool-3-thread-5] but has failed to stop it. This is very likely to create a memory leak.
