Selenium RC clears storedVars between testCases -- workaround

I can't believe that this bug has been around since 2009 and still hasn't been fixed.

http://jira.openqa.org/browse/SRC-712">
Selenium RC doesn't recall stored vars from another testcase within a single testsuite

and a similar bug (but incorrect title) in:  http://jira.openqa.org/browse/SEL-605">SEL 605

I couldn't get Krishnan Kannan's workaround with -userExtensions to work (because I'm blindly copy-pasting, not understanding at any depth how it's supposed to work), so am now using a custom edited selenium-server-2.0.5.jar until I can either get the user extension to work or it gets fixed upstream :-(
