Re: DevAppServer Creation Fails With IBM JDK

I don't know if this is related but we run ibm jdk and in order to get gwt working for us we have to remove the *gwtar files from gwt-user.jar and clean out the gwt-unitCache folder in our workspace.

Installed GWT today and ran through the steps in the Getting Started guide.  When I tried to debug the sample I created as a web application, GWT was unable to create the DevAppServer:

I'm using the IBM Java 7 SDK.  Why is GWT making calls directly to classes in the sun packages and not, in this case, java.net?
