Subject Re: Compiler Versionl question
Date Sat, 31 Mar 2012 13:45:29 GMT
As it turned out, I was simply pointing to a 1.6 JDK but was trying to 
use some 1.7 features. I pointed at a 1.7 JDK and now the message has 
gone away.

I figured this out not too long after posting the question but forgot to 
mention it on the mailing list.

Thanks for your reply!
