--- Comment #4 from Sebastien Tardif <sebtar...@ncf.ca> --- Thanks for the link. It does mentions for an attempt to provide parallel classloading for Tomcat 7 but that doesn't seem to have happened. http-bio-31680-exec-41 is running loading a class. Any of the stack below will come to that state at some point. So you can pick anyone as a representative of http-bio-31680-exec-41. My application does work, it's just 15x slower than with GlassFish. The thread dump was provided to show that we do have different code doing class lookup, about different classes, all waiting. The code triggering loading is not custom but JDK JAXB. My understanding is that the problem is well understood, so a use case is not adding anything here. Everybody know it's creating problems, that doesn't look good, but it have been declared too hard to fix, and so progress stopped 4 years ago. Previous deadlock issues may have been related to Java JDK version before 7 -> http://docs.oracle.com/javase/7/docs/technotes/guides/lang/cl-mt.html Optimized class loader -> https://github.com/jboss-modules/jboss-modules/blob/master/src/main/java/org/jboss/modules/ConcurrentClassLoader.java Java 7 was release July 28, 2011. -- 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
