GWT Leopard Fixed

Wednesday, November 07, 2007
Google Web Toolkit now works on Mac OS 10.5. Google's team posted a link to the unofficial test build of GWT 1.4.61 in the issue tracker (comment #46):
http://code.google.com/p/google-web-toolkit/issues/detail?id=1792#c46

According to the post, this is not an official release and is still under testing, so report any problems to GWT Issue 1792. I've tested the patch on Leopard with the Hello World, Kitchen Sink, and my GWTFlow applications. Everything works great. I had no problems launching GWT applications via shell scripts or debugging them from Eclipse. Other users report similar successes with IntelliJ JetBrains and Cypal Studio.

If you're interested in the gory details of the GWT/Leopard incompatibilities, view the history in the issue notes. The first two problems stemmed from changes in Apple's AWT subsystem initialization and Webkit's Carbon interop. The third problem was a ClassLoader bug in Leopard's 1.5 JVM when starting Java with -XstartOnFirstThread.

Many thanks to Google's Kelly Norton* and members of the GWT community for tracking this issue down.
