A DESCRIPTION OF THE PROBLEM :
This is the same issue reported in 7180349. I am reporting it separately as it was unclear if it was a javac or groovy issue, and that bug is requesting more info, and I am unable to update it.



REGRESSION. Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
It is unclear how to recreate this. I am running Sonar via maven on our muti-module app.

ie., mvn clean sonar:sonar - the error occurs during test compile phase of our webapp.
