/**
* Proxy for PreparedStatementMock object to test QueryContext.
* <br/>
* We need to implement this mock with an invocation handler as the implemented
* interface java.sql.PreparedStatement has changed from Java 5 to Java 6. With
* this change not only new methods have been added but also new classes has been
* introduced which are referenced by PreparedStatement.
