I'm using JBoss Profiler 1.0 RC3 on JBoss 4.0.3SP1 AS. All set up procedures have been done. Both front-end and JMS agent can be accessed. BUT when I click the "invoke" button of "void activete()" in console to run profiler, the result is"the page cannot be displayed". An error happens and terminates the JBoss server. Error INFO: JBoss Profiler: Initializing DataGathering | # | # An unexpected error has been detected by HotSpot Virtual Machine: | # | # Internal Error (50415241.................), pid=3556, tid=5924 | # | # Java VM HotSpot<TM> 1.4.2_17 Any idea to solve this problem? Any similar experience to share? Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4231842#...
