> The test used to fail occasionally before the test method was commented out by JCR-4006:
> {noformat}
> junit.framework.AssertionFailedError: rec2 should be null
> 	at junit.framework.Assert.fail(Assert.java:50)
> 	at junit.framework.Assert.assertTrue(Assert.java:20)
> 	at junit.framework.Assert.assertNull(Assert.java:237)
> 	at org.apache.jackrabbit.core.data.TestCaseBase.doDeleteRecordTest(TestCaseBase.java:327)
> 	at org.apache.jackrabbit.core.data.TestCaseBase.testDeleteRecord(TestCaseBase.java:192)
> {noformat}
> The main reason of this error is because the underlying backend uses asynchronous writing threads by default, which is not working well when extending {{org.apache.jackrabbit.core.data.TestCaseBase}} as mentioned in JCR-4005.
> So, it seems better to fix it again like the following like how JCR-4005 was fixed:
> - Restore the commented out block ({{TestCachingFDS.testDeleteRecord()}}).
> - Provide an option to disable asynchronous writing in all the related backend implementations. e.g., disable it if {{asyncWritePoolSize}} is zero or smaller.
> - In unit tests, simply disable async writing.
