One issue is that we are too aggressively creating the entire JarHandler structure. All the profile service is doing is asking the deploy directory VirtualFile for its children. It does nother with these other than ask for the last modified time. Either lazily initializing the JarHandler or/and tracking previously extracted jars would fix the excessive creation of tmp jars.
