Robbie Gemmell created ARTEMIS-3654:
---------------------------------------
Summary: AllClassesTest can create and fail to close a
LibaioContext instance
Key: ARTEMIS-3654
URL: https://issues.apache.org/jira/browse/ARTEMIS-3654
Project: ActiveMQ Artemis
Issue Type: Test
Components: Tests
Affects Versions: 2.20.0
Reporter: Robbie Gemmell
AllClassesTest tries to create objects with random args as part of its check.
It never closes these.
A cascading test failure was noticed due to the static TotalMaxIO check done
before/after ActiveMQTestBase based tests to check for AIO context leaks. As
AllClassesTest was the only test to run in the JVM before this happened, it
essentially had to be the cause.
The behaviour would fit with it generally failing to create the LibaioContext
instance due to its internal checks, but succeeding this one time, then not
closing it.
