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://issues.jboss.org/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 at org.jboss.serial.classmetamodel.StreamingClass.readStream(StreamingClass.java:98) at org.jboss.serial.objectmetamodel.ObjectDescriptorFactory.readObjectDescriptionFromStreaming(ObjectDescriptorFactory.java:381) at org.jboss.serial.objectmetamodel.ObjectDescriptorFactory.objectFromDescription(ObjectDescriptorFactory.java:82) at org.jboss.serial.objectmetamodel.DataContainer$DataContainerDirectInput.readObject(DataContainer.java:643) at org.jboss.serial.persister.RegularObjectPersister.readSlotWithFields(RegularObjectPersister.java:353) at org.jboss.serial.persister.ObjectInputStreamProxy.defaultReadObject(ObjectInputStreamProxy.java:78) at java.math.BigDecimal.readObject(Unknown Source) ... 42 more 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().
