Tomek Rękawek commented on OAK-4828:
------------------------------------
>From what I saw, if you use MMAPed FileStore on Windows, the files are not
>released even though the FileStore is closed. That's the reason of exception.
In [r1763502|https://svn.apache.org/r1763502] I'm using a custom version of
deleteRecursively that doesn't throw exception but logs the error IO cause (so
the segment tar version can be bumped).
The root cause is worth investigating anyway. Reproduction steps:
a) create FileStore with MMAP enabled,
b) close FileStore
c) remove repository directory D
d) check if the directory D exists
On Windows either c) or d) fails.
> oak-ugrade tests fail with segment tar 0.0.12 (on Windows)
