    Description

      java.lang.ClassLoader and sun.misc.Launcher have explicit dependencies on the Kernel code. While the performance impact of this is minimal (the calls basically amount to nops when the JRE is complete), it's still undesirable.

      We should restructure this so there is e.g. a system property that controls how these classes delegate, and then have the launcher set this system property to point to the relevant Kernel code when running in a Kernel environment.
