Java and Citrix
Has anyone successfully deployed a Java 1.3 application on Citrix? We've recently encountered a problem with our application not displaying correctly or hanging altogether when run via Citrix. I searched around a bit and discovered that I'm not the only one to see this kind of thing:

I also searched the forums at citrix.com - it seems that the people on the Java forums blame Citrix, whereas the people on the Citrix forums blame Java (go figure). One common suggestion that I've seen at both forums is that AWT based apps will run correctly under Citrix, whereas Swing based apps may or may not work at all depending on the version of Java and the version of Citrix.
One workaround that was suggested was to specify "-Dsun.java2d.noddraw=true" to disable Direct Draw, but our application runs on Solaris so I don't think that option is doing anything at all for us (and in fact, it had no effect in our tests).
Does anyone know where I can find a list of compatibility problems between Java and Citrix? Better yet, does anyone have any workarounds I can try? Needless to say this will be a nontrivial problem for us if it turns out that Citrix and Java/Swing are incompatible. We have a customer who has recently upgraded to our newer version (which uses Java 1.3) from our older version (which used Java 1.2), and now they have no end of display problems and crashes.
