The patch looks good to me.  If I understand correctly this may be
because we’re bootstrapping with GCJ, which implements Java 1.5.  You
can see in the log that “javac” runs with “-source 1.5 -target 5”, which
means that it assumes that the code is written in compliance with Java
1.5.  Maybe this file simply is not valid Java 1.5.

According to http://stackoverflow.com/a/8697805/519736 “@Override” is
interpreted more strictly in 1.5.  I don’t know much about Java and I
haven’t looked at the sources in question, but I guess there are
“@Override” annotations above the five method declarations.  We might be
able to just remove them.

I think this should be reported to Andrew; looks like a bug as
bootstrapping with GCJ should work for OpenJDK 6.
