> Currently, when retrieving a ClassFileStream during runtime, we call into the zip library to retrieve the stream based only on a class name. This doesn't work well if the class is in a multi-release jar under a versioned directory such as `META-INF/versions/9/Foo.class`. To address this issue, this change calls the java api `ClassLoader.getResourceAsStream()` to retrieve the stream.
> 
> Passed tiers 1 - 4 testing.
