I have several subprocesses between two Inclusive Gateways. If only two specific subprocesses are started (A and B), the following situation occurs.
When one of the processes (A) ends, the token from it goes outside and reaches the end of BPMN - without waiting for the job from another subprocess (B) to be fully executed.
At the same time, when child (B) process reaches the end, it stuck on the last activity with the error Cannot invoke “Object.equals(Object)” because “srcActivity” is null
A and B are common processes with several gateways and service tasks.
What can lead to such an error?
Stacktrace:
java.lang.NullPointerException: Cannot invoke “Object.equals(Object)” because “srcActivity” is null
