Error description
During handling of a web service response WebSphere Commerce could throw a NoSuchElementException randomly in a not reproducible way and a transaction response is not handled properly. The SystemOut.log reports the following exception: [2/14/12 11:37:31:125 UTC] 0000006d RemoteExcepti E CNTR0020E: EJB threw an unexpected (non-declared) exception during invocation of method "executeService" on bean "BeanId(WC_guest#Enablement-BaseComponentsData.jar#WebServiceEng ine, null)". Exception data: java.util.NoSuchElementException at java.util.HashMap$AbstractMapIterator.makeNext(HashMap.java:129) at java.util.HashMap$KeyIterator.next(HashMap.java:200) at java.util.AbstractCollection.toArray(AbstractCollection.java:304 ) at java.util.ArrayList.addAll(ArrayList.java:236) at com.ibm.commerce.datatype.MapBasedTypedProperty.keys(MapBasedTyp edProperty.java:85) at com.ibm.commerce.webcontroller.WebControllerHelper.mergeProperti es(WebControllerHelper.java:194) at com.ibm.commerce.command.AbstractViewCommand.mergeProperties(Abs tractViewCommand.java:142) at com.ibm.commerce.messaging.composer.Composer.getURLRecordResult( Composer.java:522) at com.ibm.commerce.messaging.composer.Composer.getURLRecordResult( Composer.java:367) ... NoSuchElementException is coming from the iterator of the default properties of the ViewRegistryEntry. This indicates that the default properties are being modified by another thread, for example StrutsRegistrySourceImpl, while this thread is iterating over it. That is an error happening due to multiple threads concurrently looking at the default properties.
Local fix

Make multiple threads accessing concurrently the default properties.
