Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V7.0 * **************************************************************** * PROBLEM DESCRIPTION: Deployment using loose configuration * * scenarios may encounter a Concurrent * * Modification exception. * **************************************************************** * RECOMMENDATION: * **************************************************************** Application deployment using loose configuration scenarios, for example, Rational Application Developer, may fail in rare instances with concurrent modification exceptions. This is due to a lack of synchronization in the loose configuration code. The exception will look similar to the following: java.util.ConcurrentModificationException at org.eclipse.emf.common.util.BasicEList$EIterator.checkModCount(B asicEList.java:1327) at org.eclipse.emf.common.util.BasicEList$EIterator.next(BasicEList .java:1275) at org.eclipse.jst.j2ee.commonarchivecore.looseconfig.internal.Loos eConfigRegister.findLooseApplicationIfLoaded_platform(LooseConfi gRegister.java:864) at org.eclipse.jst.j2ee.commonarchivecore.looseconfig.internal.Loos eConfigRegister.findLooseApplication(LooseConfigRegister.java:58 4)
Problem conclusion
Necessary synchronization was added to the loose configuration code. APAR PM77910 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.29 of WebSphere Application Server. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
