> 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.
