For jl.Module then it would be cleared if defineModules is changed to:

// export and open packages, skipped for open and automatic
// modules as they as treated as if all packages are open
if (!descriptor.isOpen() && !descriptor.isAutomatic()) {
     initExportsAndOpens(m, nameToSource, nameToModule, layer.parents());
}

That allows you to remove the check from instead initExportsAndOpens.
