Description

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.
