Moved the catch up.

Done.

We used to have the GUI client access server from different domains, so the CORS headers were
there.  As it's always hosted on the same server now, fine to remove.

It turns out this is dead code.  Removed.

Not sure where this syntax came from.  Unfolded to plain text.

Thanks, done.

And I'm not sure why they made static too. Is it necessary?

Checkstyle said all static fields should be in uppercase, so we had to rename all of them.
 The idea of making them static was to limit the number of vertices logged per worker (JVM),
instead of per partition (instance).

Sounds good.  Done.

Thanks for catching this.  It was a safeguard to prevent infinite loop that doesn't happen
in normal runs, but good to have it fixed.  Method toClass() couldn't be used as it would
create duplicate Object.class, so compared the class name instead.

Can we migrate this to Jetty in a subsequent JIRA issue?  I'm afraid we won't have the capacity
to reimplement this part for now.
