Uwe Schindler updated LUCENE-2318:
----------------------------------

    Attachment: LUCENE-2318.patch

Here the patch.

I removed almost all System.getProperty calls from tests. Only remaining are the special properties in benchmark (maybe that can be solved, too) and System.getProperty("line.separator") - but that's fine.

LuceneTestCaseJ4 now has two fields of type java.io.File:
- TEMP_DIR that is retrieved from system property "tempDir", set by ANT or, if not available from "java.io.tmpdir". By this tests will also run correctly from eclipse. This is static.
- DATA_DIR (deprecated) that is used by some contrib tests. This should not be used, instead the tests should use this.getClass().getResource/getResourceAsStream, which is also relative to the current tests. I did not change the tests to use this. DATA_DIR is detected from system property (set by ANT), else it is loaded from classpath of the *current* test class, because of that it is not static (but final) and initialized in the class ctor.

> Almost every test calls System.getProperty("tempDir") and some of them check the return value for null. In other cases the test simply fails from within eclipse.
> We should add this to LuceneTestCase(J4) as a static final constant. For enabling tests run in eclipse, we can add a fallback to ".", if the Sysprop is not defined.
