The aspects are meant for your use. Note that some of these work both inside and outside JBoss (logging, read/write locks etc.), while some leverage Jboss services and thus work only inside JBoss (security, transactions etc.)
You can find some documentation about our aspects here
If you write any interesting aspects and feel like contributing them back, feel free :-)
OK, I must be lost. I do not find anything on the logging aspects that are under org/jboss/aspects/logging
that's because there are none :)
Adrian played with writing some a little, but ditched it. I'm not a big fan if logging aspects as they are not really logging, they are tracing.
