--------------------------------
Summary: Resolve the nondeterminism of
testTraceLoggingForBulkUpdates() caused by order-specific assertion
Key: OAK-11989
URL: https://issues.apache.org/jira/browse/OAK-11989
Project: Jackrabbit Oak
Issue Type: Bug
Components: docs, documentmk
Reporter: Yakun Wang
The test function testTraceLoggingForBulkUpdates() in
MultiDocumentStoreTest.java shows a non-deterministic behavior when the
execution order is changed. The test sometimes fails with AssertionError. The
root cause is that failedUpdates is returned as a set by SetUtils.difference().
When this set is converted to a string for logging in the TRACE log, the order
of elements is non-deterministic. However, testTraceLoggingForBulkUpdates()
checks the elements in a specific order as follows
`assertTrue(logCustomizer.getLogs().get(0).contains("failure for [" +
modifiedRow + ", " + deletedRow + "]"));`, causing the AssertionError.
