ForkedBehavior interpretation does not check for switches defined by rdseffswitch extension point.
Currently, a ForkedBehavior can only interpret actions from the PCM core.
The introduced changes from https://jira.palladio-simulator.com/browse/SIMULIZAR-90 are missing in the fork context.
I created a pull request with the necessary changes. I will link it in the comments.
Code is based on the interpretSeffs() method in RepositoryComponentSwitch.java.
