[jbosscache-dev] new jdbc cache loader (RedcdRecJDBCCacheLoader) - backward compatibility

[Mircea Markus]

Hi,

I've finished testing and the new cache loader impl
(RedcdRecJDBCCacheLoader) works fine on existing data persisted by the prev
cache loader impl(JDBCCacheLoader).

Encountered issues:

JDBCCacheLoader does not persists the root. When one performs a put("a/b/c")
on an empty loader, all the parent nodes should be created, i.e. 'a/b', 'a'
and 'a' and '/' - root is skipped currently.
RedcdRecJDBCCacheLoader relies on root being persisted, so it performs the
following logic in start:
    public void start() throws Exception
    {
        super.start();
        if (!exists(Fqn.ROOT) && getNodeCount() > 0)
        {
            put(Fqn.ROOT, new HashMap());
        }
    }

The bug still exists in JDBCCacheLoader - I'll take a look to fix it. As
Manik said, the fix shouldn't break the compatibility.

Cheers,
Mircea
