Dale Emery commented on GEODE-9638:
-----------------------------------
This test uses our custom Java compiler class to create jars. When the compiler
finishes compiling, it deletes the temporary files it created. To delete the
temporary files, it calls Apache commons `FileUtils.deleteDirectory(dir)`.
On Windows, `FileUtils` sometimes throws `DirectoryNotEmptyException` even
though it has recursively removed all of `dir`'s contents before attempting to
delete `dir`.
I don't know the specific cause of this. I suspect that `dir` or one of its
files remains locked for a short time after `dir` is cleaned. Windows is known
to refuse to delete a locked file.
I have submitted a PR to change our custom Java compiler to create its
temporary files in memory, rather than on the file system. That way there are
no file system files to delete.
