- You have a client application that uses Java and Microsoft JDBC Driver for SQL Server to connect to SQL Server.
- You upgrade Oracle Java Runtime Environment (JRE) to version 6 Update 29 or a later version.
- After you upgrade JRE, you can no longer connect to SQL Server.
In this scenario, JDBC Driver might stop responding when it is trying to open the connection. Additionally, JDBC Driver fails immediately and a call stack is generated if one of the following methods is used to encrypt connections:
- The Encrypt property is set to True in the connection URL.
- SQL Server is configured to force encryption.
- You may experience this issue if you use third-party implementations of Secure Sockets Layer (SSL)/Transport Layer Security (TLS) that contain the same behavioral change as JRE version 6 Update 29 and later versions. This change in behavior fixes a specific security issue known as "BEAST." If you are unsure whether a third-party product contains an implementation of SSL/TLS that includes this change, contact the product’s vendor.
- Any data access provider that uses the OpenSSLlibrary may also cause this issue.
