SUGGESTED FIX

we correct an outcome of Java's "signed-based world-view" during the implicit type conversion after the casting.
                                     

SUGGESTED FIX

./src/solaris/classes/sun/awt/X11/MotifDnDDropTargetProtocol.java

old:  long time_stamp = MotifDnDConstants.Swapper.getInt(data + 4, eventByteOrder);
fix:  long time_stamp = MotifDnDConstants.Swapper.getInt(data + 4, eventByteOrder) & 0xffffffffL;

--
./src/solaris/classes/sun/awt/X11/MotifDnDDragSourceProtocol.java

old:  long time = t;
fix:  long time = t & 0xffffffffL;
                                     

EVALUATION

when MotifDnDConstants.Swapper.getInt() is called from sun.awt.X11.MotifDnDDropTargetProtocol.getData() to read a timestamp, a value (32-bit unsigned int) is initially assigned to 32-bit signed int var. Hence, values that exceed (2^31)-1 are interpreted as negative.
