#Problem Description

The BPMN Spec mandates that if an Interrupting event subprocess fires, it must make sure that other event subprocesses do not fire as well.

Reproduce:

• Create process with two interrupting event subprocesses: one waiting for a message and one waiting for a signal
• Place user task afterm message start event of first event subprocess
• Start process
• Trigger message event subprocess by delivering the message. As a result the process instance is waiting in the user task after the event subprocess

=> If I send the signal now, the second event subprocess triggers. This should not be possible.

The same problem can be experienced with timer events
