> *Description of problem:*
> Jsr310 and jdk8 fasterxml modules are not available from deployment without specific jboss-deployment-structure.xml
> *How reproducible:*
> Always
> *Steps to Reproduce:*
> * This can be tested if "<module name="com.fasterxml.jackson.core.jackson-annotations"/>" is added to  ./modules/system/layers/base/com/fasterxml/jackson/datatype/jackson-datatype-jsr310/main/module.xml (see JBEAP-6673)
> # Create end-point with data types and special jdk8 types and allows 
> {code:java}
>     @GET
>     @Path("entity/get/json")
>     @Produces(MediaType.APPLICATION_JSON)
>     public DatatypeObject getJson() {
>         DatatypeObject per = new DatatypeObject();
>         per.setString("someString");
>         per.setDate(new Date());
>         per.setDuration(Duration.ofSeconds(5, 6));
>         per.setDayOfWeek(DayOfWeek.FRIDAY);
>         per.setOptionalString1(Optional.of("info at example.com"));
>         per.setOptionalString2(Optional.<String>empty());
>         return per;
>     }
> {code}
> # Implement custom ContextResolver in deployment. This code enables jsr310 and jdk8 fasterxml functionality. Example:
> {code:java}
> @Provider
> @Produces( MediaType.APPLICATION_JSON )
> public class JacksonProducer implements ContextResolver<ObjectMapper> {
>     private final ObjectMapper json;
>     public JacksonProducer() throws Exception {
>         this.json = new ObjectMapper()
>                         .findAndRegisterModules()
>                         .configure( SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false )
>                         .configure( DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false );
>     }
>     @Override
>     public ObjectMapper getContext( Class<?> objectType ) {
>         return json;
>     }
> }
> {code}
> # Http request to REST end-point
> *Actual results:*
> {noformat}
> {"string":"someString","optionalString1":{"present":true},"optionalString2":{"present":false},"duration":{"seconds":5,"zero":false,"negative":false,"units":["SECONDS","NANOS"],"nano":6},"date":"2016-10-27T13:02:11.991+0000"}
> {noformat}
> *Expected results:*
> {noformat}{"string":"someString","optionalString1":"info at example.com","optionalString2":null,"duration":"PT5.000000006S","date":"2016-10-27T13:01:03.923+0000"}
> {noformat}
> *Workaround:*
> Expected results is returned if specific jboss-deployment-structure.xml file is used:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <jboss-deployment-structure>
>     <deployment>
>         <dependencies>
>             <module name="com.fasterxml.jackson.datatype.jackson-datatype-jdk8" services="import"/>
>             <module name="com.fasterxml.jackson.datatype.jackson-datatype-jsr310" services="import"/>
>         </dependencies>
>     </deployment>
