A 12-year-old bug in JDK, still out there leaking memory in our applications →
The problem is a a classloader leak.
This is a specific type of a memory leak when classloaders cannot be unloaded (for example on Java EE application redeploys) and thus all the class definitions referenced by the classloader are left hanging in your permanent generation.
The Thread blocking our classloader to be garbage collected is referenced from the sun.net.www.http.KeepAliveCache instance field keepAliveTimer.
This issue is fixed in JDK 7.
