Michael Neale updated JCR-778:
------------------------------

    Attachment: jackrabbit-JCR-778.zip

OK here is a project to reproduce - probably more longer winded then it strictly needs to be, but its hard to know what it causing it.

How to reproduce (any platform, and it included JR 1.2.2 and a version of LazyQueryResultImpl to print out a stack trace):

Unzip, import into eclipse (has project files), open RulesRepositoryTest.java, run test. Repeat up to 10 or 20 times, and you should see a failre every now and then.

It seems to be looking for an index directory that does NOT exist - if you remove indexing, it will still fail as it looks for a content item that does not exist.

Note, this creates the database each time (and the first time sets up node type definitions) - by wiping it clean, thats the only thing slightly unusual about this.

> About 1 in ten times, I get the error as shown in the stack trace below. This happens when I run test, or when I start the app. The only way to resolve (when testing) seems to be to blow away the repository. 
> It always happens at the point the query manager is accessed (triggering the query subsystem to start up). It DOES NOT cause an exception to be thrown back to the caller, I just noticed it in the logs. Basically the queries return NO data at all (and show up as test failures of course). 
> In each case when I startup the system/test, if the repository exists I use it, and (for tests) clean it by deleting the root node of the user content, and then starting again, otherwise there is nothing that exciting.
> Please let me know if more info is needed.
