Are you redeploying your applications? I think there was a JDK bug that
caused spurious references to classloaders and classes to be held in such

Check the "bugs fixed" lists on java.sun.com

I checked java.sun.com for "bugs" but didn't found any relevant one
for my case.

Might have been
6636650 java classes_lang (cl) Resurrected ClassLoaders can still have children
fixed in 1.6.0_17 but bug details are no{t, longer} public.

PS please don't quote signatures.
