ClassLoader.getResource for a .class resource is checked to detect if

RuntimeMXBean.isBootClassPathSupported() returns false.
So, isSupportedJDK will be false.
Better solution would be to check if "jrt" nio file system is
available & use the same to check and/or read .class files of JDK
classes.
That will work but it might be better to look at
java.lang.reflect.Module#getResourceAsStream as this will work for
resources in both named and unnamed modules (for unnamed modules then it
works like ClassLoader#getResourceAsStream). The summary on this is that
the ClassLoader#getResourceXXX methods will locate resources on the
class path as before, it's just that they don't locate resources in
named modules.
