JDBCCacheLoader? Was: [jbosscache-dev] Re: JDBCClassLoader bug

[Manik Surtani]

I see.  Fixing the old impl (let's call this JDBCCacheLoader and the  
new one IndexingJDBCCacheLoader to prevent confusion) to persist the  
root will break running systems though, I fear.

I do think this should be fixed in the JDBCCacheLoader though;  
perhaps a param like "persist.root = true" but by default it should  
NOT persist the root so it doesn't break existing systems.

Or will it even break existing systems?  Am I being unnecessarily  
careful here?
