> ClusterGroup.forNodeId checks *id* in a loop instead of *id0*:
> {code:java}
>                 for (UUID id0 : ids) {
>                     if (contains(id))
>                         nodeIds.add(id0);
>                 }
> {code}

> The following unit test demonstrates the problem:
> {code:java}
>     @Test
>     public void testProjectionWithBadId() {
>         ClusterNode locNode = ignite.cluster().localNode();
>         ClusterGroup prj = ignite.cluster().forNodeId(UUID.randomUUID(), locNode.id());
>         Collection<ClusterNode> nodes = prj.nodes();
>         assertEquals(1, nodes.size());
>     }
> {code}
> (add to GridProjectionForCachesSelfTest)
