[jbossts-issues] [JBoss JIRA] (JBTM-2953) Support asynchronous LRA participants

[Michael Musgrove (Jira)]

     [ https://issues.jboss.org/browse/JBTM-2953?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Musgrove closed JBTM-2953.
----------------------------------
    Resolution: Done


The implementation passes the relevant TCK tests defined as examples in the spec:

https://github.com/eclipse/microprofile-lra/blob/master/spec/src/main/asciidoc/microprofile-lra-spec.adoc#reactive-support

and as TCK tests:

https://github.com/eclipse/microprofile-lra/blob/master/tck/src/main/java/org/eclipse/microprofile/lra/tck/TckContextTests.java#L215

and as participants:

https://github.com/eclipse/microprofile-lra/blob/master/tck/src/main/java/org/eclipse/microprofile/lra/tck/participant/api/ContextTckResource.java#L286

>          Components: LRA
>    Affects Versions: 5.7.1.Final
>            Reporter: Michael Musgrove

> When an asynchronous jax-rs method is annotated as an LRA (ie has the @LRA annotation), for example:
> {code}
> @GET
> @LRA
>      public void someAction(@Suspended AsyncResponse ar) throws InterruptedException {
>          ...
>      }
> {code}
> the LRA filter does not respect the asynchronous nature of the call. 
> What needs to happen is for LRA jax-rs filter (ServerLRAFilter.java) to issue an asynchronous join request to the coordinator and to link that future to the jax-rs resource AsyncResponse callback.
> And since the ServerLRAFilter cannot immediately supply the LRAId to the resource method we also need a method on LRAClient analogous to getCurrent but which returns a Future for the lra id.
