jbossts14 is compiled with jdk 1.4 and intended to support AS 4.2. It does not have JDBC3. Apart from that the codebase for a given tag is currently the same as for the jbossts build, which is compiled with jdk 5 and intended for AS 5.0 Building that version is a bit more work, so I don't do it for every CR, which is why it's currently lagging slightly. You can use the jbossts14 build in AS 5, but you won't get support for JDBC 3 specific methods in the transactional database driver.
