There are some utility classes like the graph classes in the jbossbuild module that I would like to move into common, and update to support generics. Some of the existing util classes should be updated with jdk5 implementations and generic support as well.
Once we get the current svn refactored, we should create a 2.0 branch (or make it the trunk) for this. The current refactored code should be under a 1.0 branch.
