jTDS is severely lacking in features. AFAIK it stayed on JDBC 3.0 / J2EE 1.3. This is quite outdated for for todays world an is likely going to cause issues with current frameworks and libraries.
Fair enough, though I haven't run into (m)any situations where the driver not supporting JDBC 4.X has caused problems.
Now that Microsoft's JDBC driver is open source and on Maven Central I might switch to it, though thankfully MSSQL is starting to lose favor in my team as we become more familiar with PostgreSQL.
