Problem with Java/Matlab

Hi,

apart from the problems mentioned in the Wiki
(http://awesome.naquadah.org/wiki/Problems_with_Java), which I could
successfully solve, I have additional problems when using Matlab
within awesome:

The first problem is that, when switching between tags, and returning
to the tag where matlab lives, all matlab windows are unfocused. I
cannot switch focus with mod+j/k and even clicking one of Matlab's
windows will not focus it. What works is to click one of Matlab's
windows and then clicking another of Matlab's windows. The second one
will then get focus and things will work as usual until you switch
away from the tag. What also works is to maximize a window and then
unmaximize it again...

Secondly, if I maximize one of Matlab's windows, I can switch between
the windows, and they have focus in whe wibox tasklist, but they don't
have the border around them that focused windows usually have.

This was with two Matlab windows. If I have one Matlab window and
another window (urxvt for instance) in a tag and I maximize one of
them, I can switch between them, and they will change focus, but the
Matlab window will always stay in the background, hidden behind the
urxtv window...

I'm using awesome 3.4.11-2 on Arch Linux.

Any help with this would be much appreciated!
