---------------------------------------------
Summary: Original exception is hidden when there are too many
requests
Key: APEXCORE-665
URL: https://issues.apache.org/jira/browse/APEXCORE-665
Project: Apache Apex Core
Issue Type: Bug
Reporter: Munagala V. Ramanath
Priority: Minor
The data structure to hold requests is a CircularBuffer of hardcoded size 1024
in OperatorContext. This causes an exception when the number of requests
exceeds this number but it gets hidden by a second exception.
The call sequence in StreamingContainer is something like this:
main
--> heartbeatLoop
--> processHeartbeatResponse
--> processNodeRequests
--> OperatorContext.request
--> adds request to requests which is a fixed size CircularBuffer of size 1024
Generates Exception
finally clause in main catches it and throws another exception !
--> teardown
--> deactivate
--> shutdown
--> OperatorContext.request
--> Results in a new exception because it tries to add another request to an
already full CircularBuffer !
catch clause in main sends exception stacktrace of second exception back to app
