Description Kurt Seifried 2017-05-26 14:36:17 EDT 
When submitting for certificate enrollment, Google Chrome cuts off the certreq field in the submission. This causes a null pointer exception that causes the CA to crash. This can also be reproduced using Firefox by directly passing the request to the servelet without the certreq field.
