---------------------------------
Summary: AMQP: Clean up unit test start / stop code, excessive
thread creation casuse slowdowns.
Key: AMQ-5604
URL: https://issues.apache.org/jira/browse/AMQ-5604
Project: ActiveMQ
Issue Type: Sub-task
Components: AMQP
Affects Versions: 5.11.0, 5.11.1
Reporter: Timothy Bish
Assignee: Timothy Bish
Priority: Minor
Fix For: 5.12.0
The current test support code uses single thread executor instances as defense
against hangs on test tearDown but is a bit aggressive with it as it also does
Broker start / stop in an executor and never reuses them so every test run
requires three to four threads just to start stop. There's also some thread
interruption bits that blindly interrupt anything that is not the main thread
which could lead to problems with the JUnit threads etc. We can reduce this
all down to one executor to close the legacy QPid JMS client connection which
does sometimes hang on close.
This shaves off anywhere from 1.5 to 2 minutes from the test run.
