Comment (by mevenson):
From this overview of openjdk9 changes https://wiki.openjdk.java.net/display/Adoption/JDK+9+Outreach:
{{{ Changes due primarily to the introduction of the Java Platform Module System may affect code which
expects that applying the public modifier to an API element guarantees that the element will be everywhere accessible, or expects to use ClassLoader::getResource* and Class::getResource* methods to read JDK-internal resources, or expects to use the java.lang.reflect.AccessibleObject::setAccessible method to gain access to members of packages that are not exported by their defining modules, or as JVM TI agents expect to be able to instrument Java code that runs early in the startup of the run-time environment.
Existing code that invokes ClassLoader::getSystemClassLoader and blindly casts the result to URLClassLoader, or does the same thing with the parent of that class loader, might not work correctly.
Existing custom class loaders that delegate directly to the bootstrap class loader might not work correctly; they should be updated to delegate to the extension class loader. }}}
