-----------------------------------
Summary: UIMA-AS: service returns wrong performance metrics
Key: UIMA-5178
URL: https://issues.apache.org/jira/browse/UIMA-5178
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Affects Versions: 2.8.1AS
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.9.0AS
The JmsOutputChannel uses a single instance of XStream to serialize CAS
performance metrics. When multiple threads serialize metrics at the same time
there is a chance that the data becomes corrupted. Synchronize access to the
xstream instance when serializing metrics
