[Stephen F Northover]

Hi Kevin,

Please review the lambdification of the rt-tests component. You are 
welcome to apply the patch, but there are numerous changes and they are 
all automatic. If you have outstanding changes, please commit them and I 
will lambdify once more.

Jira: https://javafx-jira.kenai.com/browse/RT-35197
Webrev: See patch is in the JIRA
