Bug #: 52850 Summary: Various miscellaneous fixes to Tomcat Memory Leak Detection code Product: Tomcat 7 Version: trunk Platform: PC OS/Version: Windows Server 2003 Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: dev@tomcat.apache.org ReportedBy: kelap...@gmail.com Classification: Unclassified Problem Description - ---------------------- Tomcat memory leak detection has the following issues - Most of the detection and fixing code has been tested ONLY on Sun JVMs. A lot of the reflection based code does not work with the IBM JDK. - Tests in tomcat7.source\test\org\apache\catalina\loader do not seem to run successfully and are incomplete for all the protection that Tomcat provides for classloader memory leaks. - For some categories of threadlocal memory leaks the key and value are not displayed correctly in the warning messages; particularly ones dealing with indirect references to threadlocals - org.apache.catalina.loader.WebappClassLoader.loadedByThisOrChild(Object) incorrectly traverses the object classloader hierarchy instead of the current (this) classloader hierarchy Problem Conclusion - -------------------- - After extensive testing with the IBM JDKs, I have cleaned up and sanitized some of the reflection code to stop executors, timers, threads etc on the IBM JDK - Added new tests for detecting threadlocal leaks and thread leaks - Better ThreadLocal leak reporting with corrected loadedByThisOrChild method and addition of expungeStaleEntries method - Make code more resilient in certain leak detection scenarios. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
