      If you use JDK 6 update19 or newer, and your application sends or receives <classname>java.io.File</classname> objects, a serialization exception may occur. This exception can also happen if you are using clustering with a stateful session containing a <classname>java.io.File</classname> object.

      To prevent this exception, a new property has been added. Set the system property <property>-Dorg.jboss.serial.SYNC_SERIALIZATION_BINARY_FORMATS=true</property>, for all JBoss instances that communicate with each other.

    Description

      JBoss Serialization fails because the JDK 6 update 19 changes the way java.io.File deserializes. java.io.File uses defaultWriteObject when serializing and uses defaultReadObject prior to update 19. For 19 and higher, it uses defaultWriteObject when serializing and uses readFields when deserializing. JBoss Serialzation's format is not binary compatiable when using defaultWriteObject and then using readFields. This causes EJB clients that are running in the same JVM as the EJB to fail with the ClassCastException below.

      JDK 6_18
      private synchronized void readObject(java.io.ObjectInputStream s)
      throws IOException, ClassNotFoundException

      { s.defaultReadObject(); char sep = s.readChar(); // read the previous separator char if (sep != separatorChar) this.path = this.path.replace(sep, separatorChar); this.path = fs.normalize(this.path); this.prefixLength = fs.prefixLength(this.path); }

      ****************************************************************************************
      JDK 6_19
      private synchronized void readObject(java.io.ObjectInputStream s)
      throws IOException, ClassNotFoundException

      { ObjectInputStream.GetField fields = s.readFields(); String pathField = (String)fields.get("path", null); char sep = s.readChar(); // read the previous separator char if (sep != separatorChar) pathField = pathField.replace(sep, separatorChar); this.path = fs.normalize(pathField); this.prefixLength = fs.prefixLength(this.path); }

      The exception is:
