[jboss-jira] [JBoss JIRA] (JGRP-2469) GossipRouter: make GraalVM-compliant

[Bela Ban (Jira)]

    [ https://issues.redhat.com/browse/JGRP-2469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14040984#comment-14040984 ] 

Bela Ban commented on JGRP-2469:
--------------------------------

Didn't even need the {{init()}} method, as GossipRouter doesn't need any build time initialization; it starts up quickly enough (couple of millis), plus this way, we can have all of the command line options:
{noformat}
[belasmac] /Users/bela$ gossiprouter
setrlimit to increase file descriptor limit failed, errno 22

GossipRouter started in 1 ms listening on 0.0.0.0:12001
{noformat}

> Currently, GossipRouter starts threads in the constructor. This prohibits it to run under GraalVM as a native image, as threads cannot be started at build time.
> Create a separate method {{init()}}, which is called after the constructor and after all attributes have been set, but before {{start()}}.
> Alternative: use a builder:
> {code:java}
> router=GossipRouter.builder().setXX().build(); // creates server
> router.start();
> {code}
