[Seasar-user:10040] [S2Mai] 2回目のメール送信時にNullPointerException

[出羽 健一]

出羽と申します。

S2Maiで１回目はメール送信できるにも関わらず、２回目だと以下のようなNullPointerExceptionが出てしまいます。

バージョンは 0.9.2 です。

SMARTデプロイ（ホットデプロイ）を使わずに、S2コンテナ経由からMaiインターフェースを取得した場合はこのようなエラーは起きていませんでした。

しかし、http://d.hatena.ne.jp/rokugen/20061211 のページを見ながらSMART deployのための設定をして、SMART deploy 環境で動作させると、表題のような現象が出るようになりました。　

なお、Seasar 2.4.7 での変更（※１）を考慮して、creator.dicon は次のようにしてあります。
　<component class="org.seasar.mai.creator.MaiCreator" >
　　<property name="enableInterface">true</property>
　</component>

この件について、何か分かることがあれば、アドバイスを頂きたいので、
どうぞ宜しくお願いします。
