Pipeline Syntax Generator throws 500 on merge before build

Issue Type:	Bug
Assignee:	Unassigned
Components:	core
Created:	2016/Jun/20 6:44 PM
Environment:	Centos 7, Jenkins 2.10
Priority:	Minor
Reporter:	Joe Roberts

Didn't know which component to assign this to, so went with core.

When attempting to use the pipeline syntax generator with "checkout: General SCM" and "Additional Behaviors" set to "Merge before build", upon clicking the "Generate Groovy" button the textbox is never populated with the snippet. Console shows an internal server error. Tailing the log showed this:
