Can't build 8.4-701 on Fedora - Mailing list pgsql-jdbc

I get this error while trying to do $subject:

    [javac] 194. ERROR in /home/tgl/rpmwork/BUILD/postgresql-jdbc-8.4.701/org/postgresql/gss/MakeGSS.java
    [javac]  (at line 21)
    [javac]     import com.sun.security.auth.callback.TextCallbackHandler;
    [javac]            ^^^^^^^^^^^^^^^^
    [javac] The import com.sun.security cannot be resolved

(There are a boatload of warnings, too, but this is the only error.)

I'm not in the least surprised that the Java environment on Fedora
would be missing such a class, but what do I do about it?

            regards, tom lane
