Title:
  Strange behaviors in gij-5 (compared to  other JVMs)

Status in gcc-5 package in Ubuntu:
  Won't Fix

Bug description:
  We are applying differential testing on four JVMs. We modified class
  files in several real-world benchmarks and see the different behaviors
  of different JVMs. We had found two possible bugs in gij-5.

  For one class file, GIJ-5 reports a ClassFormatError, while other JVMs can run it successfully.
  For the other one, GIJ-5 throws VerifyError while other JVMs can run it successfully.

  Details for reproducing the bug and the class file is posted on
  https://github.com/fuzzy000/JVMBugs/tree/master/GIJ-5, we hope that
  you can check it out.
