      Description



      Name: inR10064 Date: 03/12/2001



      java.lang.Class.getMethods() returns not all inherited methods of interface.
      The sample program ( see source below ) shows that for interface
      org.w3c.dom.CDATASection the method returns only method splitText(int)
      defined in direct superinterface org.w3c.dom.Text .
      But the org.w3c.dom.Text inherits a lot of methods defined in superinterfaces.

      This wrong behaviour is detected for all merlin builds starting from
      jdk 1.4.0beta-build51.

      The bug seems do not affect reflection of classes, interfaces only.
