java.lang.AssertionError: System properties invariant violated.

[Roman Chyla <ro...@gmail.com>]

Hello,

(Please excuse cross-posting, my problem is with a solr component, but
the underlying issue is inside the lucene test-framework)

I am porting 3x unittests to the solr/lucene trunk. My unittests are
OK and pass, but in the end fail because the new rule checks for
modifier properties. I know what the problem is, I am creating new
system properties in the @beforeClass, but I think I need to do it
there, because the project loads C library before initializing tests.

Anybody knows how to work around it cleanly? There is a property that
can be set to ignore certain names
(LuceneTestCase.IGNORED_INVARIANT_PROPERTIES), but unfortunately it is
declared as private.

Thank you,

  Roman

Thank you! I haven't really understood the LuceneTestCase.classRules
before this.

The purpose ot the assertion is to verify that no code being tested is 
modifying system properties -- if you are setting hte properties yourself 
in some @BeforeClass methods, just use System.clearProperty to unset them 
in corrisponding @AfterClass methods
