Hey Brian, great question. The reality is that this catalog was hidden away in 
the File Manager test suite inside of TestDataSourceCatalog. There was 
something wiggy about the DataSourceCatalog code that Hypersonic SQL didn't 
like so I had to extend DataSourceCatalog for internal testing since it made 
sense to use Hypersonic SQL for that (could load up the DBMS in memory, etc.) I 
know that there was like 1 method that used incompatible SQL syntax that 
Hypersonic SQL didn't like. Then when I overrode that one method, I had to 
override like 4-5 others to inject my subclass method into the call chain for 
that which is what you see in the patch. It seems that DataSourceCatalog has 
since evolved and it's entirely possible that it would support Hypersonic SQL 
now, so here's what I see as 2 options:

1. we try and simply remove Hypersonic SQL catalog period, and then see if the 
TestDataSourceCatalog passes. If it does, this issue is moot and I will close 
this ReviewBoard and the issue.

2. If #1 doesn't succeed, and suggests changes, we could:
  a) flow those changes into DataSourceCatalog -- someone would have to have 
time to do that :) It also could happen later; or
  b) suggest that since this catalog exists and we know it works, temporarily 
in 0.4 and ongoing until someone refactors or improves DataSourceCatalog ship 
the HypersonicSQLFriendlyCatalog for folks who want to use it.

Sound right? Thoughts?
