このエラーが発生する理由がわかりません。冗長なライブラリなどをクリーンアップしてみました。
実行しようとするとエラーが発生します:
mongo = new Mongo(Host, port);
面白いことに、IDE(IntelliJ)で作成したユニットテストを実行できますが、Tomcatで実行しようとすると次のようになります。

Jdk 7、Tomcat 7.0.27、maven 3.0.3を使用しています。
これは、バイトコードレベルのエラーのようです。たぶん、Tomcatサーバーに同じライブラリの2つのバージョンがあります。
JBossでこの問題が発生した場合、JBossはRESTeasy REST実装をデフォルトとしてバンドルしているため、独自のRESTライブラリをEAR/WARファイルでは、デプロイされたライブラリが機能するためにデフォルトのRESTeasyを無効にする必要があります。
