> There is a bug in JAAS that caused users group membership not dynamically loading at runtime. Specifically, when I used the org.apache.activemq.jaas.PropertiesLoginModule with reload=true, changes in user name and password were reflected in connections after the changes, but changes in group membership was not reloaded/picked up by new connections.
> The configuration of my broker xml and users.properties, groups.properties, as well as the login.config files are attached.
> The problem was repeatable always.
> The cause of the problem was identified as the groups membership was cached and the cache was not cleared (reloaded) after the groups.properties file change.
> The fix is to add one line of code in the org.apache.activemq.jaas.ReloadableProperties.java class.
> The src code with the fix for org.apache.activemq.jaas.ReloadableProperties.java is attached in the ticket as well.
> Please verify the fix and merge this one line of code change in org.apache.activemq.jaas.ReloadableProperties.java class in src branches for 5.13.0 as I tested the problem with 5.13.0 only. The fix should be carried forward and retroactively merged into previous versions as well.
> There is no negative impact on software or any noticeable impact on server performance.
