>                 Key: LUCENE-2349
>                 URL: https://issues.apache.org/jira/browse/LUCENE-2349
>             Project: Lucene - Java
>          Issue Type: Test
>          Components: Build
>    Affects Versions: 3.1
>            Reporter: Robert Muir
>
> We cannot safely use parallel tests (LUCENE-1709) because some test classes try to use temporary directories with the same name.
> So if these two happen to run at the same time, they conflict.
> For example TestIndexReader has code like this:
> {code}
> File dirFile = new File(TEMP_DIR, "testIndex");
> {code}
> But TestCompoundFile has similar code:
> {code}
> File file = new File(TEMP_DIR, "testIndex");
> {code}
> If both these classes run at the same time, there will be problems.
> If we want to use parallel tests safely, we have to fix this use of the static TEMP_DIR which does not include any unique name of the test.
> Ideally we can do this without changing a lot of test code, especially backwards.
