Hi Lisa,

Please review the lambdification of the toys component. You are welcome 
to apply the patch, but there are numerous changes and they are all 
automatic.  If you have outstanding changes, please coordinate with me 
and I will re-lambdify to include the changes.

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