I'm following Getting Started with Red Hat Developer Studio v 1.0 beta1. In section 3.2 when I try to open home.xhtml it fails and the error message is:
"Can't start the AWT because Java was started on the first thread. Make sure StartOnFirstThread is not specified in your application's Info.plist or on the command line"
So I opened Eclipse package contents and Contents/info.plist does not set StartOnFirstThread but Contents/MacOS/eclipse.ini does. I removed it and relaunched Eclipse but got the same error.
apparently leopard has a java bug :(
