[Seasar-user:19913] [SAStruts]Actionクラスのpublicメソッドに関して

[IZUNO Tadashi]

いづのです。

sa-struts-blankで以下の様なactionを作成した場合、エラーが発生してしまします。
この理由を調べていたのですが、よく分からないので教えていただけますか。

■action
public class IndexAction {

    @Execute(validator = false)
    public String index() {
        return "start.jsp";
    }

    public String getHoge() {
        throw new RuntimeException();
    }
}

上記actionにアクセスすると、jspなどから一切参照していない状況ですが、getHoge()が実行されてしまい、RuntimeExceptionが発生してしまいます。
AOPが関係している程度は読めたのですが、何故実行までしているのかが分からず悩んでいます。アドバイスなどあればよろしくお願いします。

環境は以下の通りです。
Seasar2.4.42
SAStruts 1.0.4-sp8

長くなって申し訳ないですが、以下にログを添付します。
