Gradle not working on Jigsaw

[Cédric Champeau]

2 things:
- Groovy uses ASM, but it's relocated, and used internally by Groovy.
Groovy will fail if it tries to parse a Java 9 class file, that's for sure.
- Gradle also uses ASM, a different version, that also has the version
parsing problem, but at every place we use ClassReader, we use a wrapper
[1] to workaround this.

There's no relation between the 2: Groovy uses ASM for its own business,
and Gradle too.
