[jboss-jira] [JBoss JIRA] (JBSER-115) 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.

Brad Maxwell commented on JBSER-115:
------------------------------------

Actually, this is just related.  The lesser fields issue, is an issue with compatible change.  JBSER-128 may or may not help.

> 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().
