Grails 1.1 and "Address family not supported by protocol family: bind"

Hi folks,

with IntelliJ IDEA 8.1 or the Diana #9757 (running on windows vista) I get the following error when I try to start a Grails 1.1-app:

Server failed to start: java.net.SocketException: Address family not supported by protocol family: bind

This error occurs also with fresh created 1.1 apps. Using Grails 1.0.4 or Grails 1.1 from the commandline everything works fine.

Any suggestions?

Cheers
