Hi Andy,
I'm suspecting on either a file not being really deleted by the JVM (i.e. IOX
or Commons IO might be failing to do that), or a hidden bug somewhere else, not
really in the compaction step.
And +1 on not blocking the release. Perhaps we could simply mark that test with
a @Ignore + a comment about a known issue, and proceed with the release.

Subject: Re: [] Release Apache Jena 3.5.0
Bruno,
Thank you for running these tests.
== What to do about the 5.3.0 release
TDB2 is marked as experimental and I don't know how else to break the
deadlock of not getting used for real except by a release. I've
hammered as much as I can.
The absence of Data-0001 suggests it is a test setup/teardown problem,
not a compaction problem. Compaction is currently quite difficult to
access (it isn't available live from Fuseki).
Options:
* Pull 5.3.0 and fix it. Unbounded wait.
* Remove TDB2 etc from 5.3.0.
* (if possible), identity the problem , then release with a note attached.
We can't have one part of Jena blocking the rest - there are still all
the incremental improvements and all the contributions to get out.
It's a compaction test and compaction does not remove data. The
previous version of the database is accessed read-only (with writers
locked out, but it is a read transaction).
However I'm biased.
Andy
