I have a fix for the NPE, but then I get the following.  I will work on an additional fix.

org.eclipse.core.runtime.AssertionFailedException: null argument:
	at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:85)

For the NPE you just need a clean workspace.  Anyone who tried using the version in HEAD for the first time wouldn't be able to!

For the second error, you need to have no projects in your workspace that have api tooling enabled.
