1. Re: Get BeanManager instance form WildFly extension
You should add a dependency to this service and obtain a particular BeanManager from there: https://github.com/wildfly/wildfly/blob/master/weld/src/main/java/org/jboss/as/weld/WeldBootstrapService.java

2. Re: Re: Get BeanManager instance form WildFly extension
What exactly means to
add a dependency to this service
?
I've tried to add line
<module name="org.jboss.as.weld" />
in module descriptror (module.xml) dependencies. This cause
serviceRegistry.getService(WeldBootstrapService.SERVICE_NAME)
to return null. If I added
<module name="org.jboss.as.weld" services="import"/>
into module.xml instead, WildFly failed to boot with exception

Thank you for any ideas.

3. Re: Re: Get BeanManager instance form WildFly extension
You need to define your own service that will have a dependency on WeldBootstrapService. A dependency is a MSC construct - see http://docs.jboss.org/jbossmsc/latest/api/org/jboss/msc/service/ServiceBuilder.html
Here is an example of WeldStartService that is registered and specifies a dependency on WeldBootstrapService: https://github.com/wildfly/wildfly/blob/master/weld/src/main/java/org/jboss/as/weld/deployment/processors/WeldDeploymentProcessor.java#L248
