Details:

PROBLEM
postgresql-jdbc-8.4-701.src/org/postgresql/gss/MakeGSS.java:21: package
com.sun.security.auth.callback does not exist
    [javac] import com.sun.security.auth.callback.TextCallbackHandler;
    [javac]                                      ^
    [javac] Note: Some input files use or override a deprecated API.
    [javac] Note: Recompile with -Xlint:deprecation for details.
    [javac] Note: Some input files use unchecked or unsafe operations.
    [javac] Note: Recompile with -Xlint:unchecked for details.
    [javac] 1 error

SOLUTION
Remove the import line (the class is not used). You should not rely on Sun's
internal packages.
