问题
I set up my javaagent in the like this:
-javaagent:/usr/pkg/tomcat/lib/aspectjweaver-1.7.3.jar
But it does not work, so I would be interested to have a look at the logs. What can I add to javaagent if I want to get log messages? (stacktrace, which classes were loaded etc...)
I beleive "options" should be used for this.
The documentation says:
implementations with a command-line interface, an agent is started by adding this option to the command-line:
-javaagent:jarpath[=options]
jarpath is the path to the agent JAR file. options is the agent options
What exactly should I write within the square brackets? "Log"? "Debug"? Something else? I know its lame but I can't find the correct syntax.

this needs to be added
-Daj.weaving.verbose=true
