----------------------------------------
Summary: LongBufferPoolTest burn test fails assertion
Key: CASSANDRA-14790
URL: https://issues.apache.org/jira/browse/CASSANDRA-14790
Project: Cassandra
Issue Type: Test
Components: Testing
Environment: Run under macOS 10.13.6, with patch (attached, but also
https://github.com/jonmeredith/cassandra/tree/failing-burn-test)
Reporter: Jon Meredith
Attachments: 0001-Add-burn-testsome-target-to-build.xml.patch,
0002-Initialize-before-running-LongBufferPoolTest.patch
The LongBufferPoolTest from the burn tests fails with an assertion error. I
added a build target to run individual burn tests, and \{jasobrown} gave a fix
for the uninitialized test setup (attached), however the test now fails on an
assertion about recycling buffers.
To reproduce (with patch applied)
{{
ant burn-testsome
-Dtest.name=org.apache.cassandra.utils.memory.LongBufferPoolTest
-Dtest.methods=testAllocate
}}
Output
{{

All major branches from 3.0 and later have issues, however the trunk branch
also warns about references not being released before the reference is garbage
collected.

Perhaps the environment is not being set up correctly for the tests.
