    I can confirm this is a new error. Gradle 3.0 works with b119, but
    not b136. And from what I can see, this is *not* going to be trivial
    to fix. Best I could get now is:
    Caused by: java.lang.IllegalAccessException: class
    org.gradle.internal.reflect.JavaMethod cannot access a member of
    class java.lang.ClassLoader (in module java.base) with modifiers
    "protected"

    Which is f* annoying.

This one is a new bug/feature,
it's part of what we have called 'stronger' (not strong) encapsulation
i.e. most of the classes of java.* disallow setAccessible, before that
only internal packages were disallowing setAccessible.

so setAccessible is forbidden, but a subclass from a different module 
can access the method... strange new rules. Anyway... was there a thread 
on jigsaw-dev about this? I would like to reread the proposal

For your specific bug, you can use ClassLoader.getDefinedPackages() or
classloader.getUnamedModule().getPackages() instead.

of course with the disadvantage that these are JDK9 only methods.
