[jira] [Commented] (AMQ-9185) java.lang.NullPointerException: Cannot invoke "String.length()" because "replacement" is null
[ https://issues.apache.org/jira/browse/AMQ-9185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17643143#comment-17643143 ]
Jean-Baptiste Onofré commented on AMQ-9185:
-------------------------------------------
OK, the problem is because you start ActiveMQ with the wrapper (and not the activemq script).
ActiveMQ 5.17.3 introduced a new JOLOKIA_CONF env variable (jolokia.conf system property) with the path to the Jolokia access file. Both bin/activemq.bat and bin/activemq scripts have been updated but I forgot to update wrapper configuration.
A simple workaround is to add the JOLOKIA_CONF in the wrapper configuration. I will fix that.
