This issue is not closed yet. It's not simply a matter of installing the Ganymede SR1. I installed Oxygen XML's XML plugin (com.oxygenxml.editor_9.3.0) in the dropins/ directory and I see the same errors as earlier in the post all over again. I am definitely using the version of the plugin for Eclipse 3.4. The only work-around is to remove the Oxygen eclipse plugin from dropins/. I really would like to use the Oxygen XML plugin in conjunction with Tools 3 but right now I can't. This same plugin works with previous versions of JBoss Tools (i.e. v2).
