-----------------------------------
Summary: Fix UIMA-AS CAS accounting to prevent loosing CASes
Key: UIMA-3001
URL: https://issues.apache.org/jira/browse/UIMA-3001
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Affects Versions: 2.4.0AS
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.4.1AS
In complex scenarios involving many CMs and nested aggregates the uima-as fails
to account for CASes correctly. In scenarios where the parent and child flow
together, the uima-as can double decrement child count of the ancestor CAS
causing it to leave an aggregate while its children are still in play. Such
scenario may lead to NullPointerException and a hang.
