Hi, thanks for the replies and sorry for the delay, it took me some time to extract the application part which throws the VerifyError. Sure you can have access to the APK and to the sources as well - if they are of any need. The APK can be found here: http://vsis-www.informatik.uni-hamburg.de/projects/jadex-android/AndroidVerifyTest.apk And the whole eclipse project, containing the sources, here: http://vsis-www.informatik.uni-hamburg.de/projects/jadex-android/AndroidVerifyTest.rar
Before filing a bug, I would feel much better if someone else could have a look and approve that there's really something not working as it should. If you have a look at the sources, don't let all the classes confuse you, the Activity test.verify.AndroidVerifyTestActivity is the entrypoint which simply instantiates the Class upon which the VerifyError is throws. All the other classes and packages are just dependencies.
