             Summary: Parameter substitution (MacroExpander) Map expand issue
                 Key: SOLR-9740
                 URL: https://issues.apache.org/jira/browse/SOLR-9740
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 6.0.1
            Reporter: Erik Hatcher


{code}
  @Test
  public void testMap() {
    final Map<String,String[]> request = new HashMap<String,String[]>();
    request.put("fq", new String[] {"${one_ref}","two"});
    request.put("one_ref",new String[] {"one"});
    Map expanded = MacroExpander.expand(request);
    assertEquals("one", ((String[])expanded.get("fq"))[0]);
    assertEquals("two", ((String[]) expanded.get("fq"))[1]);
  }
{code}

fails with `java.lang.ArrayIndexOutOfBoundsException` because the resultant `expanded` structure only has a single "fq" value of "one".  "two" got eaten.
