So the leak is fixed, but unfortunately there's a side effect : it broke webapp B eviction timer.
(TODO: file a bug report to make the clearReferencesStopTimerThread optional and disabled by default)
Note: as of 6.0.24, by default tomcat stops threads of class java.util.TimerThread whose context classloader is the WebAppClassLoader of the app being stopped. It does not stop other threads, it only warns about them. It can try to stop them if the clearReferencesStopThreads option of the standard context is set to true.
