I think it's important to support these as soon as possible. It seems obvious that this is going to come without asking for it. As you, at sun staff are going a great job around jruby: no need to ask for obvious feature... we know that it will be done some day (no emergency). But, about GUI tool kit, one thing that would be realy (realy) great is to port the standard Tk tool kit to java. this would make it possible to migrate native Ruby/Tk application to Jruby. The big part of this work seems to already be done by Bruce Johnson with it's swank package (port of tk to java for use with jacl (port of TCL language to java) - http://www.onemoonscientific.com/swank/index.html - https://swank.dev.java.net/ - http://wiki.tcl.tk/2858 If Tk whould be port to java, then Tk would be easier to install for jruby than for ruby!) About other Gui toolkit, it seems that there is some confusion between true Gui user interface with complex event handling abilities (key, mouse, ...) and power canvas drawing features with event binding (like Tk and other) and just html forms like toolkit with some graphic capabilities. I think it's easiest to switch a programm from one (stuctures or oo) language to another language, than to move from one Gui system to another one in the same language. So the choice of a Gui toolkit is important!

Yes I confirm the great startup improvemnt of the last jruby version, but I had to find some inconvenient of jruby ower ruby (but the big one is about native library bindings like Tk!) -- Maurice
