RE: [tptp-tracing-profiling-tools-dev] Java Profiler makes myJ2EE/JBoss app inconsistent in standalone mode

Hi,

Please provide us with the following information:

- The version and vendor of the JVM you are using.

- The 3^rd-party technologies your J2EE application uses (e.g, Hibernate? anything else?)

- O/S version (Windows, Linux, …) and processor architecture (including whether it is 32 or 64 bit).

This problem probably happens as a result of the byte code instrumentation the JVMTI Profiler is doing in order to track your application. You may have found a problem with our implementation.

You can try to filter-out the JBoss and Hibernate classes (and any other system classes you probably don’t really care about) and see if it helps.

To do that, create a regular text file, and define a filter set similar to the following:

myapppackage.* * INCLUDE

* * EXCLUDE

Where “myapppackage” refers to the top-level package of your application. The exact format of the filter file is specified in the TPTP documentation under “Profiling your application in standalone mode”.

Add the following argument to the –agentlib:… Java option: filters=<full path to the filter text file>

Example: -agentlib:JPIBootLoader:JPIAgent:server=standalone,filters=filters.txt;CGProf

Then try to profile your application with these filters enabled and see whether the problem persists.

HTH,

Asaf

Subject: [tptp-tracing-profiling-tools-dev] Java Profiler makes myJ2EE/JBoss app inconsistent in standalone mode

Dear All

I'm trying to profile in standalone mode an application running on a jboss server (3.2.7).

To use the Java Profiler, I have to call the application with the -agentlib:JPIBootLoader=JPIAgent:server=standalone;CGProf

parameter. Well, I've added this in the JAVA_OPTS configuration on the run.bat in jboss.

This application is a J2EE app, with EJB 2.1, and classloader share between the webapplication (app.war) and the ejb classloader (app.ear and framework.ear).

If I start the application without profile, it works fine, but when I try to start profiling, the profiler works correctly, but mades the application inconsistent - the application in profiling throws the following error on startup:
