[jboss-jira] [JBoss JIRA] Commented: (JBCL-17) New ClassLoader not finding generated classes in the bootstrap classloader

New ClassLoader not finding generated classes in the bootstrap classloader -------------------------------------------------------------------------- Key: JBCL-17 URL: https://jira.jboss.org/jira/browse/JBCL-17 Project: JBoss ClassLoader Issue Type: Bug Components: ClassLoader Affects Versions: JBossCL.2.0.0.Beta12 Reporter: Adrian Brock Assignee: Adrian Brock Fix For: JBossCL.2.0.0.CR1 Attachments: jboss-classloader.jar An optimisation in the new classloader is causing a backwards compatibility problem. When we load classes from the parent (bootstrap) classloader, we first check to see whether we can getResource() on the class file. This avoids excessive locking when many threads are trying to loadClass() on that classloader. However, if the class is a runtime generated class against that classloader getResource() will return null, leading to a ClassNotFoundException. While we've always done this optimization for JBoss ClassLoaders, it looks like we can't to do this non-jboss classloaders and maintain backwards compatibility.
