             Summary: ClassConfigurator: use constructors rather than Classes in map
                 Key: JGRP-2048
                 URL: https://issues.jboss.org/browse/JGRP-2048
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 4.0


Investigate whether use of {{Constructor}} as values in the maps rather than {{Class<?>}} improves performance. {{Class.newInstance()}} does cache the constructor, but there's a security check that's executed once, so using the constructor may improve perf.
Also, if a class doesn't have an empty constructor, using {{Class.newInstance()}} would throw an exception, whereas using constructors would detect this at load time.
