Build Identifier: I20100608-0911

Eclipse C/C++ Development Tools SDK

Version: 7.0.0.201006141710
Build id: 201006141710

I get the following NPE. However i did not even open a CDT project.
Instead this exceptions happens when I am working with XML/WST stuff.
I have both (CDT and XML/WST plugins deployed in the same eclipse installation of course, however the CDT plugin should NOT be active ???)

!STACK 0

I am using the org.eclipsecon.tutorial371example.contentassist from eclipsecon 2009 and start the plugin (eclipse runtime instance). then the NPE happens.

Interestingly several cdt plugins are active despite that fact that I am using a JDT project, e.g. my registry-view shows as active: (in a JDT project!) cdt.core, cdt.debug.*, cdt.make.ui, cdt.ui, cdt.managedbuilder.core
