I'm not having a problem with either catalog. With the vars.xml catalog, 
calling getVariables() on any of the datasets I get a list with one variable, 
clivi - "atmosphere_cloud_ice_content".

Are the catalogs you included what you got from the server 
(http://server/thredds/.../*.xml)? Or what's on disk on the server?

The ToolsUI I'm looking at was built 2008-11-25 02:50:22. So a few months after 
yours. I don't see any changes in the catalog objects or the parsing between 
those build dates.

Can you give us some details on what you are doing when you see this problem? 
How are you parsing the catalog? Are you calling InvCatalogFactory.readXML()?
