NullPointerException in "XtextReconcilerJob"

[borisbrodski]

Editing Specs I get from time to time following exception:

!ENTRY org.eclipse.core.jobs 4 2 2014-07-22 10:36:32.759

This one comes as I pushed enter after typing fact "test it" { in following Spec:

package test

describe "Test extension mehtod" {
    extension MyExtension = new MyExtension
    
    fact "test it" {
        
    }
    
    def test() {
        
    } 

}

MyExtension looks like this:

package test;

public class MyExtension {
    public void method1() {
        
    }
}

Everything was typed from scratch in a brand new workspace and a brand new single project.

Same issue is affecting me. With same versions.
