Hi, I'm getting the following stacktrace on running ElasticSearch (Spring Data) Application. Anyone know the cause of this error? INFO: Illegal access: this web application instance has been stopped already. Could not load org.elasticsearch.cluster.routing.RoutingService$1. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact. java.lang.IllegalStateException at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1599) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1558) at org.elasticsearch.cluster.routing.RoutingService.reroute(RoutingService.java:142) at org.elasticsearch.cluster.routing.RoutingService.access$200(RoutingService.java:51) at org.elasticsearch.cluster.routing.RoutingService$RoutingTableUpdater.run(RoutingService.java:163) at org.elasticsearch.threadpool.ThreadPool$LoggingRunnable.run(ThreadPool.java:530) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:351) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:178) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:178) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

From the error message it looks like your webapp has stopped and ES, probably while shutting down is trying to log something which leads to class loading which causes the message and exception by Tomcat (which prevent the loading from happening). You should probably find out what causes the webapp to close in the first place.
