Uwe Schindler commented on LUCENE-4332:
---------------------------------------
Hi,
I looked into the reports (somehow the report for Lucene "core" is missing?):
My problem with pitest is the following (and that really makes me afraid, so I
will not run it on my jenkins server at all!): It manipulates the codeby adding
random modifications to the Lucene bytecode. As Lucene is a heavy file-system
related stuff, it can happen that the code removes some code part or changes
the parameters of a method call (it also does this!), so it could suddenly
delete or modify files outside the working copy (e.g. in our heavy crazy code
deleting index files). Damage on the O/S can be prevented by running the tests
as a separate user, but it can still crash and corrupt my whole Jenkins
installation.
