Exception while deserialization of java.math.BigInteger in Sun JRE 1.6.0_14 if serialized using a previous version e.g. JRE 1.6.0_13. 
--------------------------------------------------------------------------------------------------------------------------------------

                 Key: JBSER-115
                 URL: https://jira.jboss.org/jira/browse/JBSER-115
             Project: JBoss Serialization
          Issue Type: Bug
    Affects Versions: 1.0.3 GA
         Environment: Deserializing client:
- OS: Windows XP SP3 (32Bit)
- JRE 1.6.0_14

Serializing Server:
- OS: Linux Suse Enterprise (64 Bit)
- JDK 1.6.0_13 (64 Bit)
            Reporter: Mattias Neuling
            Assignee: Clebert Suconic


Failure while deserilizing java.math.BigInteger in java.math.BigDecimal on client side:
Stacktrace:
 java.io.IOException: Current classpath has lesser fields on java.math.BigInteger than its original version

In JDK 1.6.0_14 java.math.BigInteger has one field more than in previous versions. Serialization without JBoss Serialization is no problem since it implements the methods #readObject() and #writeObject().
