JDI: ReferenceType.methods() returns methods inherited from interface

    Details

    • Subcomponent:
    • CPU:
      sparc
    • OS:
      solaris_7

      Description



      Name: abR10010 Date: 12/03/2000




      The Java Debug Interface specification for ReferenceType.methods()
      method says:
      "...
      Returns a list containing each Method declared directly in this type.
      Inherited methods are not included.
      ..."

      But the nsk/jdi/ReferenceType/methods/methods001 test
      shows that the ReferenceType.methods() method for checked
      class returns methods inherited by this class from the
      implemented interface but not declared in the checked class itself.
      Moreover the each such method has the checked class instead
      of the implemented interface as the declaring class.

      For the methods inherited by checked class from the extended super class
      the methods() method runs correctly: these methods are not included in
      the Methods List returned by the methods() method.

      This happens on both Solaris-Sparc and Win32.

      To reproduce the bug on Solaris run doit.sh in
      /net/sqesvr/export/vsn/GammaBase/Bugs/<this bug number>.

      The first parameter for doit.sh should be JDK root directory
      (e.g. /java/jdk1.4/solsparc) and the other parameter(s) -
      VM option(s) (optional).
        
      See log:

      % doit.sh /export/java/dest/jdk1.4.0beta-b42/solsparc
      java version "1.4.0beta"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0beta-b42)
      Java HotSpot(TM) Client VM (build 1.4beta-B42, mixed mode)

      See the fragment of declaration of the checked class used by
      the nsk methods001 test:

      ===============================
      abstract class ClassForCheck extends SuperClassForCheck implements InterfaceForCheck {

          ...

      }

      abstract class SuperClassForCheck {

          static void s_super_void_method(long l) {}
          static long s_super_prim_method(long l) {return 100;}
          static Object s_super_ref_method(Object obj) {return new Object();}

          void i_super_void_method(long l) {}
          long i_super_prim_method(long l) {return 100;}
          Object i_super_ref_method(Object obj) {return new Object();}

          ...

      }

      interface InterfaceForCheck {

          void i_interf_void_method(long l);
          long i_interf_prim_method(long l);
          Object i_interf_ref_method(Object obj);

          ...

      }
