Ac= cording to [[http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=3D4957990|t= his page]] it should have been fixed with java 6u16 but actually it was not= . It seems to be fixed with 6u21 (documented [[http://download.java.net/jdk= 6/6u21/promoted/b03/changes/JDK6u21.list.html|here]] and verified by the au= thor of this wiki page). * [[http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=3D6916498|Sun bug= 6916498]] - An exception can keep a classloader in memory if the stack tra= ce that was recorded when it was created contains a reference to one of its= classes. Some fixes have been made in tomcat (see [[https://issues.apache.= org/bugzilla/show_bug.cgi?id=3D50460|BZ 50460]]), but some library or JRE c= ode may still create a leak that is undetected by tools because of this JVM= bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@tomcat.apache.org For additional commands, e-mail: dev-help@tomcat.apache.org
