[jboss-jira] [JBoss JIRA] Closed: (EJBTHREE-969) EJB3Deployer locking jars in deploy dir

EJB3Deployer locking jars in deploy dir --------------------------------------- Key: EJBTHREE-969 URL: http://jira.jboss.com/jira/browse/EJBTHREE-969 Project: EJB 3.0 Issue Type: Bug Affects Versions: AS 4.2.0 GA Reporter: Brian Stansberry Assigned To: Carlo de Wolf Priority: Blocker Fix For: AS 5.0.0.Beta3, AS 4.2.1.GA In chasing down JBPAPP-171 I found that JBoss' deployment process tends to lock files in the deploy dir on Windows. (The farm dir as well, which is just a specialized form of deploy dir.) Traced it down to the EJB3Deployer.accepts() functionality, particularly the hasEjbAnnotation() method. The first line in that method Iterator it = ArchiveBrowser.getBrowser(di.url, new ClassFileFilter()); is causing the original jar in deploy to be scanned for annotations, rather than the copy in the server/.../tmp dir. That scan results in Windows filesystem locks on the deploy dir jar. Not always but seems like roughly 1/2 the time. Changing that line to the following made the problem go away: Iterator it = ArchiveBrowser.getBrowser(di.localUrl, new ClassFileFilter()); di.localUrl points to the tmp dir copy of the deployment.
