aspectj error after 12.1 upgrade

Hi all:

Just upgraded to 12.1 from 12.0.4 (I think) and now instead of a warning I am getting an error releating to aspect.
I have a maven project compiled using Java 1.6  (this is set as source and target in the pom as well.) Also, I am using aspectj 1.6.8 also source and target of 1.6 in the pom aspectj compiler configuration.

Whenever I do a re-build on the project I get the following error message. Any thoughts, ideas or help on this is really appreciated!
