Answer 1

ProGuard has not been updated yet to support Java 8.

An issue has already been raised against ProGuard.

Eric Lafortune (ProGuard developer) noted back in October 2013

I'm very busy at the moment, so realistically I won't be able to complete this in the short term, sorry. I'm keeping an eye on the developments though.

ProGuard probably works on class files that only use older features if you change or disable ClassUtil#checkVersionNumbers.
