Error description
The processing of an annotated class which implements an interface defined in a separate jar file can cause a ConcurrentModificationException. During annotations processing, the steps of determining which annotated classes are to be processed examines the interfaces of the candidate target classes. That step of examining interfaces is causing a late load of an interface which contains annotations. The late load updates the annotation targets collections, which leads to the ConcurrentModificationException. Eg: ------------------------------- 0000001d annotations E Merge Processing Failure java.util.ConcurrentModificationException at java.util.HashMap$AbstractMapIterator.checkConcurrentMod(HashMap .java:122) at java.util.HashMap$AbstractMapIterator.makeNext(HashMap.java:127) at java.util.HashMap$ValueIterator.next(HashMap.java:212) at com.ibm.ws.amm.scan.AnnotationScannerImpl.getClassAnnotationTarg ets(AnnotationScannerImpl.java:303) at com.ibm.wsspi.amm.merge.AbstractMergeAction.mergeClassTargets(Ab stractMergeAction.java:320) at com.ibm.wsspi.amm.merge.AbstractMergeAction.merge(AbstractMergeA ction.java:123) at com.ibm.ws.amm.AnnotativeMetadataManagerImpl.performMergeOperati ons(AnnotativeMetadataManagerImpl.java:504) at com.ibm.ws.amm.AnnotativeMetadataManagerImpl.merge(AnnotativeMet adataManagerImpl.java:269) ----------------------------------

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server deploying applications which use * * annotations. * **************************************************************** * PROBLEM DESCRIPTION: A ConcurrentModificationException is * * logged from annotations processing * * while deploying an application. * **************************************************************** * RECOMMENDATION: * **************************************************************** The processing of an annotated class which implements an interface defined in a separate jar file, where the interface is also annotated, causes a ConcurrentModificationException to be written to server log files. For example: 0000001d annotations E Merge Processing Failure java.util.ConcurrentModificationException at java.util.HashMap$AbstractMapIterator.checkConcurrentMod(HashMap .java:122) at java.util.HashMap$AbstractMapIterator.makeNext(HashMap.java:127) at java.util.HashMap$ValueIterator.next(HashMap.java:212) at com.ibm.ws.amm.scan.AnnotationScannerImpl.getClassAnnotationTarg ets(AnnotationScannerImpl.java:303) at com.ibm.wsspi.amm.merge.AbstractMergeAction.mergeClassTargets(Ab stractMergeAction.java:320) at com.ibm.wsspi.amm.merge.AbstractMergeAction.merge(AbstractMergeA ction.java:123) at com.ibm.ws.amm.AnnotativeMetadataManagerImpl.performMergeOperati ons(AnnotativeMetadataManagerImpl.java:504) at com.ibm.ws.amm.AnnotativeMetadataManagerImpl.merge(AnnotativeMet adataManagerImpl.java:269) The exception does not cause the deployment to fail, but is written to server logs. The exception does mean that steps of processing the application metadata may be incomplete. The features of an application which encounter the problem are: *) A module of the application is enabled for Java Enterprise Edition 5 or higher, and is enabled for annotations processing (is not metadata-complete). *) The module contains an annotated class which implements an interface which is defined outside of the module. For example, the class might have an EJB annotation and might implement an interface defined in an application library jar file. *) The interface has an annotation.
Problem conclusion
A code update was made to prevent the concurrent modification exception. The fix for this APAR is currently targeted for inclusion in fix packs 7.0.0.25, 8.0.0.4, and 8.5.0.1.
