Stackmap frame errors when building the aspectj project with Java 1.7

I had a project which used aspectj and it was building fine with Java 1.6. When I updated it to Java 1.7 I saw the following error.

Fix 

The default compliance level for aspectj-maven-plugin is 1.4 according to http://mojo.codehaus.org/aspectj-maven-plugin/compile-mojo.html#complianceLevel. Since I did not have that tag specified, the build was using the default value. Once I inserted the tag into the configuration, the build was successful.
