JVMTI Spec: Atomicity of RedefineClasses should be specified

    Details

    • Subcomponent:
    • CPU:
      generic
    • OS:
      generic

      Description

      The JVMTI spec for RedefineClasses should state something like:
      - if an error code is returned (eg, because the redefine
        operation failed for one of the classes), then logically,
        the VM is in the same state as if the RedefineClasses call had
        not occured -ie, none of the other classes specified in the
        call have been redefined

      - After the first occurance of a call to a method gets to a new version of
        the method in a redefined class, all other calls to methods
        that have also been redefined will also go to new versions.
        IE, it would be illegal if
        - the redefine operation changed methods m1 and m2
        - the JVMTI implmentation installed the new version of m1
          and then let user code execute
        - the user code called m1 and got the new version
        - a call to m2 then occured and got to the old version instead
          of the new version.
