We have a major problem with JDK9
InputStream classData = classLoader.getResourceAsStream(path);

does not work when the path is to a resource in a module. This is causing many test frameworks like javaassist and jmockit to fail causing a large number of our tests to fail.

This is on the JSR 376 issues list:

but we need a fix now.
