----------------------------------------
Summary: Bogus exception when response from parallel UIMA-AS
annotator is received by UIMA runtime before all requests to the annotators in
the parallel step are sent
Key: UIMA-3643
URL: https://issues.apache.org/jira/browse/UIMA-3643
Project: UIMA
Issue Type: Bug
Affects Versions: 2.4.0AS
Reporter: Guillermo Averboch
I have 3 UIMA-AS annotators in a parallel step. None of the annotators are
modifying anything that already exists in the CAS. Most times things work well,
but I randomly get a "preexisting FS encountered but not allowed exception".
Looking at the UIMA logs (setting the log level for org.apache.uima to ALL) it
becomes clear what's happening:
--> request goes to annotator 1
--> request goes to annotator 2
<-- response received from annotator 1
--> request goes to annotator 3 (CAS appears to contain information received
from annotator 1)
...
<-- response received from annotator 3 -- bogus "preexisting FS but not
allowed" exception is thrown
Workaround that seems to work (but which I can't really depend on) is to order
the parallel steps from slower to faster
