>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 2.6.0
>            Reporter: Johan Stenberg

> [https://activemq.apache.org/artemis/docs/latest/wildcard-syntax.html] states that the
{{#}} wildcard character means _"match any sequence of *zero* or more words"_. This however
is only true if the wild card is the last character in a wildcard expression. If any word
comes after the wildcard character then the actual behavior is _"match any sequence of *one*
or more words"_
> This means, the pattern {{topics.#.FOO}} matches {{topics.abc.FOO}} but not {{topics.FOO}}
> I am attaching a test case.
