JDK-4174928 - DnD between Swing Components broken for JDK 1.2 FCS build 'K' on Solaris
Description
Hi
 
  Set Up : Solaris 2.5.1 , JDK 1.2 FCS build 'K' & 'L'
  When trying DnD between Swing components i am getting  the following 
exception . This happens immediately after i initiate the drag operation. 
  In 'J' build it was working properly.Even in 'K' build DnD between Swing components works well on WIndows-Nt and Windows-95
   
 ( mouse Pressed
 starting drag )
        Exception occurred during event dispatching:
java.awt.dnd.InvalidDnDOperationException: The operation requested cannot be 
performed by the DnD system since it is not in the appropriate state

EVALUATION I am re-assigning this bug to classes_awt and to Jeff Dunn. The problem is the same as before; The X Event for the ButtonPress that Motif requires to initiate the drag operation is not available from the associated AWTEvent passed to awt_XmDnD.c:Java_sun_awt_motif_MDragSourceContextPeer_startDrag(). Without this information the drag cannot be started by Motif, this is an AWT Event problem and not D&D specific. larry.cable@Eng 1998-09-29
