Current rawhide has a severe bug that affects all Sun Java implementations including the jdk1.7.0 betas. https://bugzilla.redhat.com/show_bug.cgi?id=254144 The bug causes any Java application to die when it attempts to do graphics. The current workaround for the bug is to run icedtea. I'm not sure that there will be a resolution any time soon. If the bug isn't fixed for FC8, the release notes should clearly indicate that icedtea is the only Java implementation that will work. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
