So the problem is a change in behavior of a URLClassLoader that has a null parent class
loader. This seems like it is a big compatibility problem as classes defined by such a
class loader only have visibility into the java.base module rather than the entire
platform.
The simple fix is to pass in the new ClassLoader.getPlatformClassLoader() as the
URLClassLoader parent rather than null. However, this seems like what the ClassLoader
should be doing itself as I would expect a lot of code will break. I'll create a bug
report for the simple test case I have that shows the problem.

Subject: [wildfly-dev] common cdi-tck problem on wildfly with java 9
I'm looking into why the cdi-tck is failing to run on wildfly-10.1.0.Final-SNAPSHOT
using java 9 and a common issue that I don't see in the Java 9 Problems &
Solutions FAQ is illustrated by the following exception trace. It appears that the class
loader that org.arquillian.container.chameleon.ContainerLoader is using is associated with
the java.base module, and thus cannot see anything but the java.base classes. Once I
figure out how the class loader for java.base is being obtained I'll raise a general
FAQ for the problems/solutions doc, but I thought I might be able to work around this by
using the -XaddReads:java.sql=java.base to allow java.base to see java.sql, but it does
not work. Similarly, -XaddExports:java.sql/java.sql=java.base does not work.
Is there a check to prevent circular references or am I just not understanding how these
calls change the module graph?
