This is actually because the person who reported it had a older version of Apache http client in maven before Unirest and this was the final error:

caused by: java.lang.NoClassDefFoundError: org/apache/http/concurrent/FutureCallback
    at java.lang.invoke.MethodHandleNatives.resolve(Native Method)

It's weird that this even throws when the constructor is never invoked. We should also throw a better error which explains the problem and solution. Apache Http Client is used by lots of things and being on a old crusty version is a constant issue

make a better explanation for errors that happen when the user has a older version of Apache on the path https://github.com/Kong/unirest-java/commit/20ec053431f891e57152441565fef30b8505ae47
