Still trying to duplicate repeatibly. The issues seems to be consistantly triggered when typing a space between 'class' and 'extends'

public class[SPACE HERE]extends AbstractSomethingClass {..}

The AbstractSomethingClass was in a Maven dependancy that I removed. I went to delete the "extends AbstractSomethingClass" part, but accidentially deleted the "public class ConcreteSomethingClass" part instead. In typing it back (without removing "extends") I got this exception. 

Without saving this particular file, it seems to be 100% reproduceable. But when I copy the same source to my sandbox (Issuzilla testcase) project, I can't duplicate the exception. I will continue to try to get a good test case for this...

testcase project Bug252033: mvn project

The zipped maven project has 2 files, one .java and the .pom. 

The test case depends on you removing the dependency from the POM and saving.

Then you delete the class name ('Main') from the class.

This triggers the NPE every time.
