Yup, there it is.

I'm trying to track down what happened to it. My svn-fu is not very good.


http://svn.apache.org/viewvc?view=revision&revision=1028396

The whole JSP unloading functionality was refactored. As Konstantin remarked, Entry is now an inner class. I do hope there's no leak and the observed leak was due to a race condition I noticed in the original code. It would be very helpful, if you could check using 7.0.5.

Note that in 7.0.5 as an add-on there is also

- an option to unload JSPs by idle time

- a way to track the JSP queue behaviour via JMX

Is your Tomcat running under high load? Anything special to the JSPServlet configuration in conf/web.xml?

Rainer
