Thank you for your feedback. The Microsoft JDBC Driver for SQL Server does not yet support JRE 1.7.
We are aware of the getDate issue between our JDBC driver & JRE 1.7 and we are looking into publishing a hotfix to enable customers to move forward with non-production testing of our driver with JRE 1.7.
We will publish a link to the hotfix on our blog once available.

The hotfix is now available. http://blogs.msdn.com/b/jdbcteam/archive/2012/01/20/hotfix-available-for-date-issue-when-using-jre-1-7.aspx
Our blog also contains information on the known issues with JRE 1.6u29 & 1.6u30.
