> Should we merge this and the `lookupModule == null` early startup cases, and `assert lookupModule == refModule && refModule == Object.class.getModule()` can become `assert lookupModule == refModule && (refModule == null || refModule == Object.class.getModule())`?

It can be simpler:


            // early VM startup case, java.base not defined or module system not initialized
            if (lookupModule == null || !jdk.internal.misc.VM.isModuleSystemInited()) {
                assert lookupModule == refModule;
                return true;
            }
