#736 Proguard 6.1 beta fails to run under JDK8/9

[max-kammerer]

According to bytecode it requires JDK10+:

  Compiled from "ProGuard.java"
public class proguard.ProGuard
  minor version: 0
  major version: 54

Thanks, this was indeed a configuration error when building 6.1.0 beta1. ProGuard 6.1.0 beta2 will run on JDK 1.7 and higher. For the time being, you can quite easily build ProGuard yourself for an older JDK, with one of the build scripts.

ProGuard 6.1.0 beta2 (available now) has been compiled for Java 1.8 again. Recent JDKs seem to be pushing for higher versions.
