Avoid array allocation in SubjectCreatingPolicyInterceptor ---------------------------------------------------------- Key: JBWS-4031 URL: https://issues.jboss.org/browse/JBWS-4031 Project: JBoss Web Services Issue Type: Patch Components: jbossws-cxf Reporter: Philippe Marschall {{SubjectCreatingPolicyInterceptor#getPrincipal(Principal, Subject)}} converts a {{Set}} to an array just to get the first element. This is unnecessary and can easily be done with an {{Iterator}} which avoids the array creation.
