[jboss-jira] [JBoss JIRA] (JGRP-2048) ClassConfigurator: use constructors rather than Classes in map

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.
