Should be "cache loader is empty", of course :)

> JDBCCacheLoader uses queries with LIKE operator, but passes search patterns constructed from query parameters without concern for metacharacters like '%' and '_'. A quick test can show the problem:
> add /a/b/c
> add /a/d/c
> remove /a/_/c
> find the cache is empty.
> Fortunately the problem is apparently limited to deleteNodeSql and recursiveChildrenSql, both in JDBCCacheLoaderConfig (and not in AdjListJDBCCacheLoaderConfig).
