When I try to open a simple BPMN with extensions from the http://nccn.org namespace, the validator hangs (usually on 0%). Sometimes it completes much later, but sometimes I need to force kill eclipse in order to recover. Attached is a single bpmn file to reproduce the issue. When I change the xmlns:fake from http://nccn.org to anything else like http://fake.com, then the validator seems to work fine. I'm guessing the tool is making some kind of web request to this endpoint, and that something is going wrong on that end, but I'm not sure why that would be causing the entire tool to freeze. I assume it should be more resilient to namespaces like that. -- Configuration Details -- Product: Eclipse 4.5.0.20150621-1200 (org.eclipse.epp.package.jee.product) BPMN2 Modeler - Diagram Editor 1.2.0.201506101742 I've seen similar behavior with previous versions as well.

Sorry, was trying to update the attachment, but it looks like I can't. Basically I found that other namespaces like "https://fake.com" can create the same issue.
