Resolving no such field exception coming from use of HttpClients.createDefault.
Using defaulthttpclient, which does not result in the exception.
Note this method is deprecated under httpclient 4.3.1, which is the current pom version.
However, it is not deprecated under 4.2.1, which is also provided in wildfly.
But, for now, we leave it at 4.3.1, since it may be that REST EASY client depends on it. We will determine that in a subsequent branch.
