Hi Orsi,

I think ReflectUtil was introduced at a later point in time and this code should have been replaced by a call to that class. Could you create a JIRA issue for this and maybe add an example that shows this error?

Thanks,

I've created the JIRA issue: http://jira.codehaus.org/browse/ACT-1674
It took me some time to create an example but at the end it turned out that one of the basic examples fails because of the same exception.
I've modified the ActivitiInAction book's osgi sample and used Karaf to test it, files are attached to the issue.

I am using 5.12.1 and facing the same issue, is there a work around so that without even migrating to 5.13 we should be able to do the trick?
