[jboss-jira] [JBoss JIRA] Closed: (JBCL-100) GlobalClass Cache is inefficient

GlobalClass Cache is inefficient -------------------------------- Key: JBCL-100 URL: https://jira.jboss.org/jira/browse/JBCL-100 Project: JBoss ClassLoader Issue Type: Task Components: ClassLoader Reporter: Adrian Brock Assignee: Adrian Brock Fix For: 2.0.6.GA The globalCacheClass (and the blacklist) is inefficient in the new classloader. 1) It only caches the Loader not the class 2) Because of (1) it goes through the classloader scheduling everytime 3) When the parent is not a ClassLoaderDomain (e.g. it is the system classloader) there is no real caching of the parent classes when useLoadClassForParent=true which is the default in this case. For import-all=true, this needs changing to something more like JBoss-4.x where the classes are cached directly and the parent classes get cached also when the parent is not a ClassLoaderDomain. With the most important being the cache/blacklist checked before the lock is taken on the classloader.
