[Android-tools-devel] Bug#832568: apktool fails to run on Java 7 because it was compiled to target Java 8

[Simon Ruggier]

Package: apktool
Version: 2.1.1+dfsg-2
Severity: serious
Justification: Policy 3.5

I just installed apktool, and when I run it, it fails like so:
$ apktool
Exception in thread "main" java.lang.UnsupportedClassVersionError:

The version 52 suggests that the class was compiled to run on Java 8[1]. My
java alternative points at /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java, so
naturally, this doesn't work.
