Hi Tim,

good catch! seems like a bug introduced by SOLR-9784 . 

I think we should add a test case for this as well? We could write some additional tests in
AliasIntegrationTest ?

> Some recent refactoring seems to have introduced a bug in SolrJ's CloudSolrClient, when
it's expanding a collection list and resolving aliases, it's using the wrong local variable
for the alias lookup. This leads to an exception because the value is not an alias.
> E.g. suppose you made a request with {{&collection=x,y}} where either or both of
{{x}} and {{y}} are not real collection names but valid aliases. This will fail, incorrectly,
because the lookup is using {{x,y}} as a potential alias name lookup.
> Patch to fix this attached, which was tested locally and fixed the issue.
