[S2Container] 継承元クラスと派生クラスに同名のフィールドがあると PropertyInterType で例外が発生する問題を修正しました．

    • Type: Bug
    • Resolution: Fixed
    • Priority: Minor
    • 2.4.31
    • Affects Version/s: 2.4.30
    • Component/s: S2Container

      継承元と継承先のクラスが同名のフィールドを持っている場合、継承先のクラスに対してPropertyInterTypeを適用すると、同じ名前のgetter/setterを複数回作成しようとして例外になります。

      再現例は以下です。

      public class Test {
      public static class Aaa

      { public String someProperty; }

      public static class Bbb extends Aaa { public String someProperty; }

      public static void main(String[] args) {
      AspectWeaver weaver = new AspectWeaver(Bbb.class, Collections
      .emptyMap());
      weaver.setInterTypes(new InterType[]

      { new PropertyInterType() }

      );
      weaver.generateClass();
      }
      }

      Exception in thread "main" org.seasar.framework.exception.CannotCompileRuntimeException: [ESSR0017]例外が発生しました。理由はjavassist.bytecode.DuplicateMemberException: duplicate method: getSomeProperty in com.openknow.viewer.server.Test$Bbb$$EnhancedByS2AOP$$cdedfd
