I had a note from the Maple people and quoting: "Actually this bug applies to more then just Fedora 8. Anyone who has a Linux distribution with an updated X11 library included in it can encounter this problem. We did a little checking on this bug a while ago and we're not sure who's responsible for this; either the X11 people are or the Java people are. They know what causes the bug but they don't know how to fix it. Basically X11 is being very strict with some of the checking they do before they'll do anything with the display and Java isn't being strict enough. Sun says it's not their problem and that it's fixed." If you are using the sed edit workaround it is important to find all the files that need changing and not necessarily two files. There are other workarounds that have been suggested but it seems not all work for all people.
