java.lang.IncompatibleClassChangeError：クラスMongoの実装

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。

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。

参照： Java.lang.IncompatibleClassChangeErrorの原因は？

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。
