cucumber-jvm: cucumber-java8 fails on OpenJDK 1.8.0

Cucumber-Java8 depends on internals of the implementation of Oracle’s JDK8. When I started experimenting with it I just always got the following exception:

The test project causing this output is available at https://github.com/mawis/cucumber-java8-test

While it fails on OpenJDK8 it works without problems on Oracle JDK8. I consider this to be a bug, as I don’t think that cucumber should depend on a specific implementation of the compiler.
