Possible solution to this bug
Description of problem:
Package fails to build using Java 8. I have first discovered this on ppc. I have tried to build package using mock locally(on x86_64) to rawhide, as rawhide ships jdk8 build fails same way as on ppc.
Steps to Reproduce:
I have made bit of digging to this, and I have found fix for this. Patch in attachment defines constant in Optcodes.java for Java 8 and modifies ClassReader.java to use it. This change makes build with jdk8 finish successfully.
Please verify this patch.
