Changeset 2026 for trunk/autoquest-core-usageprofiles/src/main/java/de/ugoe/cs/autoquest/usageprofiles/IStochasticProcess.java

Message:

• made generation of random sequences with an expected valid end and a predefined maximum length more robust. the generation now aborts after a user-defined number of attempts to create a valid sequence and returns an empty sequence instead.
