John, I'm not sure I understand. Compiling with JDK6 or JDK7 with 1.6 compat mode on and running ACS on JRE7 are two different things. I definitely think we should test with both JRE6 and JRE7 even in 4.1 and let the system admin make the decision on when to switch from JRE6 to JRE7. However, I don't think, at this point, we should compile with JDK7 and use JDK7 only features which forces the admin's hand in upgrading from JRE6 to JRE7.
