      Description

      In class PropertyOwnerPointer, method setValue

      The code says first

      if (parent.isContainer()) ...

      then it checks for parent not being null.

      else if (parent != null) {

      If the parent could be null the first code
      would trigger a null pointer exception.

      So I think:

      now the parent happens to be never null
      but either
      1. the (parent!=null) check is unecessary
      (I don't know the exact semantics of this class)
      2. or more probably the

      {parent.isContainer()}

      block should be put inside
      the

      {parent!=null}

      check.

      An other findbugs find.
