      An update to the way <classname>java.io.File</classname> deserialized in JDK 6 Update 19 caused a binary incompatibility in JBoss Serialization.

    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:

          Task - Represents a small unit of work that is not end-user facing. JBPAPP-6106 Update JBoss Serialization in JBoss EAP 4.3 CP10

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
