ObjectStreamClass is not thread-safe. The other io classes seem to
be OK.


Only the static variables that are set and used in thread-unsafe
methods are listed. Only methods that are thread-unsafe are listed.

/**********************************************************************/
java/io/ObjectStreamClass.java
Variable: descriptorFor
   Set and used in findDescriptorFor.
   The method insertDescriptorFor used descriptorFor and also calls

   The method lookupInternal calls findDescriptorFor from a
   synchronized block.
   The method insertDescriptorFor calls findDescriptorFor from a
   unsynchronized block.

   The constructor for ObjectStreamClass calls insertDescriptorFor
   from an unsynchronized block. So, using this method may cause
   a thread-unsafe set of descriptorFor in the routine
   findDescriptorFor.
