> with the default jaas login config - repeated login attempts lead to OOM.
> heap dump shows:
> org.apache.karaf.jaas.modules.properties.PropertiesInstaller 86,374 instances
> on investigation seems each PropertiesLogin init registers a
> PropertiesInstaller service that I don't see used.
> Unit test and possible fix (though I have no idea what a PropertiesInstaller
> service should do) attached.
