Thanks for the report... As it turns out using 1.7 to bootstrap 1.6 worked only because 1.7 is 'early access' and was using the same internal class file version as 1.6. Now that 1.7 has progressed further and its class file version has been bumped, I'm afraid that this bootstrap method is no longer valid for 1.6. More specifically the problem is that 1.7's rt.jar has class file version 51.0 and 1.6's gjc.jar is expecting a 1.6 rt.jar with class file version 50.0. Regards, -Kurt
