1.02    4663.14 org.jboss.virtual.plugins.vfs.helpers

The main things during startup are: VFS, Classloading and AOP - as you would expect.

Notice there are two calls to org.jboss.aop.asintegration.jboss5.AOPDeploymentAopMetaDataDeployer#deploy(org.jboss.deployers.vfs.spi.structure.VFSDeploymentUnit, org.jboss.aop.microcontainer.beans.metadata.AOPDeployment) in the hotspot section.

The file contains the profile of org.jboss classes only - I can do other profiles if needed.

> Boot time has gone up by 60% causing testsuite timeouts.
