Description Matthew Piggott CLA 2011-02-23 11:02:14 EST 
After updating to m2e 0.13.0.201102221506 any attempt to build the workspace resulted in errors for each project that 'configurators is null'.

Opening the Eclipse log there are a number of stack traces:

I fixed the problem:
http://git.eclipse.org/c/m2e/m2e-core.git/commit/?id=ccac2d36d92bf43058665aa83205cf0c2310ff1f

I'll keep the bug open until I add a unit test for it.
