    JNIMethodScope scope = LibGraalUtil.openScope(TruffleToLibGraalEntryPoints.class, GetNodeTypes, env);
    try (JNIMethodScope s = scope) {
        GraphInfo orig = LibGraalObjectHandles.resolve(handle, GraphInfo.class);
        String[] nodeTypes = orig.getNodeTypes(simpleNames);
        JClass componentType = FromLibGraalCalls.getJNIClass(env, String.class);
        JObjectArray res = NewObjectArray(env, nodeTypes.length, componentType, WordFactory.nullPointer());
        for (int i = 0; i < nodeTypes.length; i++) {
            SetObjectArrayElement(env, res, i, JNIUtil.createHSString(env, nodeTypes[i]));
        }
        scope.setObjectResult(res);
    } catch (Throwable t) {
        JNIExceptionWrapper.throwInHotSpot(env, t);
