Problem summary
**************************************************************** * USERS AFFECTED: Users of IBM WebSphere Application Server * * SIB / Business Object function. * **************************************************************** * PROBLEM DESCRIPTION: Service integration bus (SIB) and/or * * Business Object operations can see * * high CUP utilization. * **************************************************************** * RECOMMENDATION: * **************************************************************** When performing application operations which use SIB or Business Object functionality, high CPU usage can be seen in method "copy" of class "org.eclipse.emf.ecore.util.EcoreUtil", invoked from method "copy" from class "com.ibm.ws.bo.service.BOCopyImpl". A collected thread dump from the application server process will show a stack similar to the following: WeakHashMap.get(Object)Object+35 (line 699) org.eclipse.emf.ecore.util.FeatureMapUtil$BasicValidator$Cache.g et(org.eclipse.emf.ecore.EStructuralFeature)Boolean [compiled] +3 (line 2714) org.eclipse.emf.ecore.util.FeatureMapUtil$BasicValidator.isValid (org.eclipse.emf.ecore.EStructuralFeature)void+16 (line 2886) org.eclipse.emf.ecore.util.BasicFeatureMap.add(Object)void+95 (line 954) org.eclipse.emf.ecore.util.EcoreUtil$Copier.copyReferences()void [compiled] +388 (line 1255) org.eclipse.emf.ecore.util.EcoreUtil.copy(org.eclipse.emf.ecore.

Problem conclusion
The problem occurs because the step of copying Business Objects, which is implemented by class "EcoreUtil", performs validation of the copied objects. The validation step is expensive and is unnecessary because validation has already been performed on the Business Object which is being copied. The problem is resolved by a code update which skips the validation step when copying Business Objects. The fix for this APAR is currently targeted for inclusion in fix pack versions 7.0.0.43, 8.0.0.13, 8.5.5.12, and 9.0.0.3.
