Error description
Description: There is a problem in the WebSphere Application Server annotation scanner code that might be seen when the "com.ibm.config.annotations.scan.state" trace is enabled. This trace might be enabled when a more comprehensive trace specification such as com.ibm.*=all or com.ibm.config.annotations.*=finer is enabled. When the exception occurs, the following stack trace will be displayed in the log files: org.eclipse.jst.j2ee.commonarchivecore.internal.exception.Annota tionsProcessorException: CWWAM0001E: An exception occurred during annotation processing: java.util.ConcurrentModificationException Stack trace of nested exception: java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:934) at java.util.HashMap$ValueIterator.next(HashMap.java:962) at com.ibm.ws.amm.scan.util.info.impl.ClassInfoCache.log_delayedCla sses(ClassInfoCache.java:1793) at com.ibm.ws.amm.scan.util.info.impl.ClassInfoCache.log(ClassInfoC ache.java:1675) at com.ibm.ws.amm.scan.util.info.impl.InfoStoreImpl.log(InfoStoreIm pl.java:463) at com.ibm.ws.amm.AnnotativeMetadataManagerImpl.scan(AnnotativeMeta dataManagerImpl.java:781)
Local fix
