The lockInCache call will force the class being added as a hard reference to the "classes" cache, thus ruining the soften feature. I'm not really sure what you mean here, but toClass() is called when creating a new class so does that not need to be in the hard cache? If only in the softcache, when it is removed and somebody needs to obtain the CtClass again we would need to load it from its resource. Although in AS that would probably be fine since dynamically created classes have their bytes written to a temporary location (tempURL in AS 4, vfsmemory url in AS 5) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4239064#...
