The intention is to support 6 and on, but also use 7 features if
available. That said the servlet 3.1 Apis have a dep on some 7 classes. We have a plan to
produce a 6 specific servlet 3.0 target, just haven't gotten to it yet.
I hope you know that some classes in the core (JDBCLogHandler and ProxyHandler)
make use of Java 7 APIs.
Are you planning on using it with 6?
No plans to use Java 6 anymore. For me Java 6 is dead. I was just surprised to see
the compiler config for Java 6 and usage of Java 7 APIs.
