Daniel Kulp resolved CXF-5968.
------------------------------

       Resolution: Fixed
    Fix Version/s: 3.0.2
                   2.7.13
         Assignee: Daniel Kulp


Fixed to re-allow true/false values.   Not that true is an alias for ALWAYS=
 and false for NEVER so using the Always/Never values should work.

> The value 'true' for 'use.async.http.conduit' property seems to be conver=
ted to uppercase, then passed directly to 'valueOf' method of Enum.
> According to online documentation, such configuration should result in us=
ing AsyncHTTPConduitFactory$UseAsyncPolicy.ALWAYS by CXF.
> It works as expected in 3.0.0, having the effect of using async http clie=
nt for every request.
> It seems that using the following configuration is a valid workaround:
> {noformat}
> [...]
> =09<cxf:bus>
> =09=09[...]
> =09=09<cxf:properties>
> =09=09=09<!-- Apache AsyncHttpClient properties (http://cxf.apache.org/do=
cs/asynchronous-client-http-transport.html) -->

>             <entry key=3D"org.apache.cxf.transport.http.async.usePolicy" =
value=3D"ALWAYS" />
> =09=09</cxf:properties>
> =09</cxf:bus>
> [...]
> {noformat}
> The online documentation states that the above configuration is similar (=
not identical) to using 'use.async.http.conduit' property. What are the dif=
ferences (if any)? Is it a valid workaround?
