Hi,
i have found a workaround for this issue.
The problem is, that the class org.jbpm.userprofile.UserProfileManager has a Seam 2.2 dependency.
My solution was:
modify the sourcecode of jBPM 5.2
remove all dependencies to seam 2 in the jbpm-human-task module and add the dependency:
<dependency>
<groupId>com.thoughtworks.xstream</groupId>
<artifactId>xstream</artifactId>
<version>1.4.1</version>
</dependency>
After that, delete or modify the class:
org.jbpm.userprofile.UserProfileManager
and the test:
org.jbpm.userprofile.UserProfileManagerTest
compile
