Problem with some keys in Java apps with NX

(Sorry, my first post went to the wrong thread due to my
mistake, excuse me 
for reposting it)

Hi everybody,
we are running the nxagent on a Solaris box, and the client
on Windows with
german keyboard. Some characters like {, [, | have to be
generated with the
"AltGr" key on such a keyboard. This works fine
for all apps, xev shows the
correct events and keysyms, see below (Mode_switch is the
AltGr key)

But all Java apps we are running do *not* recognize these
chars.Instead of {
(which is on the "7" key), they simply show
"7", as if AltGr hadn't been
pressed. Very frustrating, especially if you want to write
code in a
Java-based editor (we use JEdit, and SunStudio11 as IDE).
With Java 1.6, the problem is gone, but we can't use that
due to performance
bottlenecks in that version with SunStudio :( We have to
stick with 1.4.2 or
1.5 JVM.

The problem is ONLY present in NX sessions, of course.

Does anybody here have an idea how to solve this? Do Java
apps do their own
keycode translation, not using XLib? Why is the behaviour
under NX so
different? Actually, the same misbehaviour is present if I
only use nxproxy
on both sides, without nxagent. So it seems to be a problem
of the transport
layer???

The weirdest thing is: Some keys do work with AltGr, it's
simply not
consistent. E.g. the "2" key has this xmodmap
entry:

    keycode  11 = 2 quotedbl twosuperior oneeighth

If I press AltGr-2, I get the twosuperior even in a Java
app. But
AltGr-Shift-2 does not yield oneeighth, only "2".

Now look at the "7" key:
    keycode  16 = 7 slash braceleft seveneighths
No matter what I press, I never get braceleft or
seveneighths :(

Sorry for the long post, but I'm desperate!
Any help?
