[jboss-jira] [JBoss JIRA] (WFLY-1885) ServiceActivator blocks server startup if more than 8 services - platformspecific

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-1885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12807341#comment-12807341 ] 

Paul Ferraro commented on WFLY-1885:
------------------------------------

I suspect this is merely a matter of changing the manner in which you build your SingletonService.  Use this test case as an example:
https://github.com/wildfly/wildfly/blob/master/testsuite/integration/clust/src/test/java/org/jboss/as/test/clustering/cluster/singleton/service/MyServiceActivator.java

> We try to start more than 8 services by ServiceActivator.
> We follow hasingleton quickstart.
> Server startup is blocked on Linux but not on windows (?!?).
> If we introduce a delay of e.g. 1 second, all services start correctly also on Linux:
> public void activate(ServiceActivatorContext context) {
>   ESMSSingletonServiceBase<T> service = getSingletonService();
>   log.info("ESMSService will be installed: " + service.getSingletonServiceName());
>   SingletonService<String> singleton = new SingletonService<String>(service.getSingletonServiceName(), service);
>   singleton.build(new DelegatingServiceContainer(context.getServiceTarget(), context.getServiceRegistry()))
>     .addDependency(ServerEnvironmentService.SERVICE_NAME, ServerEnvironment.class, service.env)
>     .setInitialMode(ServiceController.Mode.ACTIVE).install();
>   // TODO: diesen Workaround evtl mal beheben. 
>   // (Server startet im Moment nicht anders... zumindest nicht auf Linux! Timingproblem?)
>   try {
> 	Thread.sleep(1000);
>   } catch (InterruptedException e) {}
> Thread dump of Linux blocked server attached
