Need help to resolve Crash Report

Question

Here is my crash report.  I can login, and select a single player world, but then it stops and gives this crash report.  I've tried creating a new world, and even reinstalling minecraft but still get the same error report.  Any help would be appreciated:

Answer 1

You have not mentioned reinstall of Java - that is what you should try.

Remove all Java completely and reinstall the newest.

Thanks for your answer.  I was already running the latest update of Java, but thought I would give your suggestion a try.  I completely uninstalled all java and then reinstalled it.  I am still getting a crash report as shown below:
