Uwe Schindler commented on LUCENE-4332:
---------------------------------------
You would need a simple Security manager that allows all, except
creating/deleting some files outside a working directory. We can check this out
(by enabling a noop security manager), if it then still passes we are fine.
Then we can go forward. The security manager would only be activated by LTC
before after a test class and then disabled again. I would not restrict file
access too much. For Pitest, I would only disallow everything outside working
directory root and later disable more. I think a simple restriction to build/
dir would also help to prevent solr creating files in test-files src folder.
An all-allowing security manager is easy, template is available to extend. The
problem you are talking about are too complex security restrictions dictated by
J2EE (that limit things like creating classes or classloader) - we dont want to
do this, we only want a hook into (new FileOutputStream) and want to throw an
Exception on wrong path. If you allow all other security manager requests,
there is no issue.
