In 1.6.0_27 everything was fine. Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); Connection conn = DriverManager.getConnection( "jdbc:sqlserver://localhost:1433","sa","password"); System.out.println("connected"); Both releases have been installed with no further customizations, tests have been perfomed with identical 3-party JAR files. If SQL Server is shut down (and the socket is closed on 1433) while the program is running under 1.6.0_29 DriverManager.getConnection bails out with an exception. REGRESSION. Last worked in version 6u26 REPRODUCIBILITY : This bug can be reproduced always. CUSTOMER SUBMITTED WORKAROUND : Downgrade to JRE/JDK 6.0 Update 27
