Description of problem:

Hadoop (CDH4) has ObjectNames like this:

Hadoop:name=IPCLoggerChannel-127.0.0.1-234,service=NameNode

Unfortunately, to query, this syntax is not currently supported:

<c:simple-property name="objectName"
   default="Hadoop:name=IPCLoggerChannel-%addr%,service=NameNode" />

The solution is to allow %key% to appear within an attribute value, not as the entire value.

The changes are probably supportable in ObjectNameQueryUtility itself.

    private void buildMatchMap(String objectNameQueryTemplate) {
...
        for (String key : keys) {
            Pattern p2 = Pattern.compile("^([^=]*)=\\%(.*)\\%$");
            Matcher m2 = p2.matcher(key);

maybe change to:

            Pattern p2 = Pattern.compile("^([^=]*)=(.*\\%(.*)\\%.*)$");

etc.
