I should have been clearer in my comment. The suggestion to use a ParameterizedTest is to exercise a custom class loader using super.defineClass with different buffers (direct, heap, position != 0, ...) so that it exercises the "non-trusted" cases.

You are right that testing the platform class loader (as a trusted class loader) will require opening java.lang.
