JBoss EAP 6/7 fails to initialize with log message "WARNING: Failed to load the specified log manager class org.jboss.logmanager.LogManager" when an agent uses JUL

Issue

• Using one of the following system properties, and I get the IllegalStateException below:

-Dcom.sun.management.jmxremote=x
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false

• Getting below logManager error on startup of EAP 6.

FATAL: JBAS015957: Server boot has failed in an unrecoverable manner; exiting. See previous messages for details.

• Installed a Java agent (e.g. Wily Introscope) via the -javaagent JVM command-line parameter. When trying to boot JBoss, getting the following error stack trace:

java.lang.IllegalStateException: The LogManager was not properly installed (you must set the "java.util.logging.manager" system property to "org.jboss.logmanager.LogManager")

For reference , here is a very basic Java agent implementation http://bit.ly/UjXkN6 where the issue is easily reproducible

• JBoss fails to start after numerous attempts. The following message is captured in the logs when startup fails
