During testing of an aspect-enabled JWT application environment, a few problems were detected in which Exceptions were thrown in certain circumstances: 1. It seems there is a problem detecting missing profiles if a package is missing. The user is not notified and all aspects are removed automatically from the workflow_conf file. The only indication of the error is shown in the console 2010-07-01 15:46:42.837 org.eclipse.jwt.we.conf.model.resource.internal.ConfModelResourceManagerImpl handleResourceLoadingError SEVERE: Patchable (but won't try to patch) error loading conf model resource for ConfModel file platform:/resource/test/CaseStudy.workflow_conf while looking for expected ConfModel of model platform:/resource/test/CaseStudy.workflow (org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'de.uni-augsburg.methodology-support.mcd' not found.

Sometimes the following error is thrown when opening a workflow. The same error is thrown during saving and the workflow_conf file is not saved. Deleting the workflow_conf file fixes this problem. 01.07.2010 16:32:47 org.eclipse.jwt.we.conf.model.resource.internal.ConfModelResourceManagerImpl createConfModel WARNUNG: Error saving ConfModel platform:/resource/test/test.workflow_conf after patching it with the right enrichedModel while looking for expected ConfModel of model platform:/resource/test/test.workflow org.eclipse.emf.ecore.resource.Resource$IOWrappedException: A resource already exists on disk 'D:\eclipse_ws\jwt\runtime-New_configuration(1)\test\test.workflow_conf'. at org.eclipse.emf.ecore.resource.impl.PlatformResourceURIHandlerImpl$PlatformResourceOutputStream.flush(PlatformResourceURIHandlerImpl.java:138) at org.eclipse.emf.ecore.resource.impl.PlatformResourceURIHandlerImpl$PlatformResourceOutputStream.close(PlatformResourceURIHandlerImpl.java:90) at org.eclipse.emf.ecore.resource.impl.PlatformResourceURIHandlerImpl$WorkbenchHelper$1.close(PlatformResourceURIHandlerImpl.java:172) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(ResourceImpl.java:997) at org.eclipse.jwt.we.conf.model.resource.internal.ConfModelResourceManagerImpl.createConfModel(ConfModelResourceManagerImpl.java:348) at org.eclipse.jwt.we.conf.model.resource.internal.ConfModelResourceManagerImpl.loadConfModelOfModel(ConfModelResourceManagerImpl.java:218) at org.eclipse.jwt.we.conf.model.aspects.internal.AspectManagerImpl.getConfModel(AspectManagerImpl.java:131) 3. Removing profiles in the management tab sometimes throws a NPE in the disableProfile method in the line Profile currentProfile = (Profile) currentAspect.eContainer(); due to currentAspect being null. This can be prevented with if (currentAspect == null) continue; but I don't know if this has unwanted side effects.
