The constant was dropped before betas were even released. The reason was the
refactoring of the driver and new pluggable architecture.

In general, we maintain backward compatibility for FirebirdXXX interfaces
only (though there was one change in FirebirdConnection because of JDBC 4.0
interface, see release notes), linking to any of JayBird classes (incl.
public ones) is at your own risk. Sorry, if that was not clear from the
beginning, I will put separate page on our wiki and change the release
notes.
