Thank you Siddharth for the patch.  I think it is looking very good as a model for the recovery tests.

I updated the patch with a few changes which I am attaching as derby4249. I enabled security manager by adding the needed lines to the policy file and fixed a preexisting problem with the output when the launched method fails so that it prints the expected output strings and not just the array reference.
I also added a CleanDatabaseTestSetup decorator so that the schema objects get cleaned up. If nobody objects I will commit after I run some tests.

> It would be good to be able to start converting the store  recovery tests  or at least be able to write new recovery tests in JUnit.   We could start by writing a simple recovery test just to establish the framework.  The test should.
> -  Connect, create a table, commit and shutdown the database.
> -  fork a jvm, add one row, commit, add another row, exit  the jvm.
> -  Reconnect with the first jvm and verify that the first row is there and the second is not.
> I guess the main thing to decide is how to spawn the second jvm and check results.    I tend to think the second jvm should actually execute another JUnit test, verify the exit code (assuming a failed test has a non-zero exit code) and then put the output in the fail assertion if it fails so it shows up in the report at the end of the Suite execution.   I think we could create a test runner that takes a class and a specific test to run instead of the whole suite, so we could keep our methods consolidated in a single class for the test, but all pure conjecture at this point.  I'll have to give it a try, but wanted to first see if folks thought this was a reasonable approach.
