        * java/util/TreeMap.java (root): Don't initialize.
        (TreeMap(Comparator)): Call fabricateTree(0).
        (fabricateTree): Initialize root and size when count is 0.

Summary:  Deserialization of an empty TreeMap fails

Original Submission:  Deserialization of an empty java.util.TreeMap fails with 
a 
NullPointerException. It happens because transient field 
"root" is not initialized during deserialization. To fix:
add root = nil; to the beginning of readObject method.

I've attached a Mauve test that triggers the bug with Classpath, and passes 
with Sun's JDK 1.4.  I'll forward it to the mauve-patches mailing list also.
