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

[Thomas Frühbeck (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-1885?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Frühbeck updated WFLY-1885:
----------------------------------

    Description: 
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) {}
