Description

When I use the following Mailet/Matcher,

<mailet match="HasMailAttributeWithValueRegex=jDKIM.AUTHRESULT, fail" class="Null"/>

I get a NullPointerException as below:
Caused by: java.lang.NullPointerException
at org.apache.james.mailetcontainer.impl.jmx.MatcherManagement.getMatcherName(MatcherManagement.java:75)

This does not happen when I use the HasMailAttributeWithValue matcher though.
