Jdbc itself is also ultimately file based, what is wrong with BerkeleDB?
Is it because the JdbjeCacheLoader itself is not well written?
It seems the only choice for production would be the JDBCCacheLoader if I need persistence... is this true?
Besides the FileCacheLoader, which is not recommended (see javadoc, it explains why), I don't see any reason why NOT to use other cache loader implementations. I think docs are misleading, others?
