Hi James,
Hmm I see. One Final question. When an agent starts up with the JVM I have
seen this as well
-Xbootclasspath/p:jboss-logmanager-<VERSION>.jar;log4j-jboss-logmanager-<VERSION>.jar.
So when we don't provide these arguments at startup and the agent attaches
later, the log4j manager will not be present. So I would have to alter the
LogManager object or something like that. Changing the system property that
points to these guys is not going to make it work right? Or am I
understanding this wrong and only one of them is used (whichever is found
first).
Thanks
./Sam

Hi Sam,
It just depends if the any method on the java.util.logging.LogManager gets
invoked before JBoss Modules sets the
java.util.logging.manager=org.jboss.logmanager.LogManager system property.
This happens fairly early in the main entry point of jboss-modules.
