[aspectj-dev] Loadtime Weaving Deadlock

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

Two of our users have reported a deadlock in load-time weaving on a 1.4 VM, e.g., see http://www.glassbox.com/forum/forum/viewthread?thread=146

 

This happens in a 1.4 VM because ObjectInputStream locks sun.misc.SoftCache (used to hold verified subclasses), whereas in 1.5 they use a ConcurrentHashMap so you don’t get the deadlocking behavior. I’m thinking that the best fix for this is to somehow force ObjectInputStream to load a class before weaving so that it won’t trigger class loading during weaving. This would be a fix/work-around in the 1.4 VM adapter we’re using, so it’s not an AspectJ issue per se, but I’d value input on how to best resolve this.

 

Thanks,

Ron
