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?

I'd recommend skipping 7.0.4 and getting Tomcat 7.0.5 from svn. Mark tagged it today, so you can get it from here: http://svn.apache.org/repos/asf/tomcat/tc7.0.x/tags/TOMCAT_7_0_5/ I would expect a 7.0.5 release sometime next week. The class in question is completely removed from 7.0.5, so whatever problem was causing the apparent memory leak won't happen again - at least in that form. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

There is no such class in any current Tomcat version. Since you haven't told us which version you are using, there is little more we can do to help.
