-------------------------------------------
Summary: Setting use.async.http.conduit property causes
IllegalArgumentException
Key: CXF-5968
URL: https://issues.apache.org/jira/browse/CXF-5968
Project: CXF
Issue Type: Bug
Components: Configuration, Transports
Affects Versions: 3.0.1
Environment: SunOS 5.10
Reporter: Przemysław Ołtarzewski
After upgrading from CXF 3.0.0 to 3.0.1 we are experiencing an
IllegalArgumentException in every request from a generated client code to the
target WS, probably related to following cxf.xml fragment:
{noformat}
[...]
<cxf:bus>
[...]
<cxf:properties>
<!-- Apache AsyncHttpClient properties
(http://cxf.apache.org/docs/asynchronous-client-http-transport.html) -->
<!-- Always use Apache AsyncHttpClient for HTTP
transport -->
<entry key="use.async.http.conduit" value="true"/>
</cxf:properties>
</cxf:bus>
[...]
{noformat}
Exception:

{noformat}
The value 'true' for 'use.async.http.conduit' property seems to be converted to
uppercase, then passed directly to 'valueOf' method of Enum.
According to online documentation, such configuration should result in using
AsyncHTTPConduitFactory$UseAsyncPolicy.ALWAYS by CXF.
It works as expected in 3.0.0, having the effect of using async http client for
every request.
It seems that using the following configuration is a valid workaround:
{noformat}
[...]
<cxf:bus>
[...]
<cxf:properties>
<!-- Apache AsyncHttpClient properties
(http://cxf.apache.org/docs/asynchronous-client-http-transport.html) -->
<!-- Always use Apache AsyncHttpClient for HTTP
transport -->
<entry key="org.apache.cxf.transport.http.async.usePolicy"
value="ALWAYS" />
</cxf:properties>
</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 differences
(if any)? Is it a valid workaround?
