>Category: JBossServer Group: v3.2 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Barry M. Caceres (barrycaceres) >Assigned to: Scott M Stark (starksm) Summary: Deserialization Broken for java.lang.Class for RMI calls Initial Comment: It appears that the code that handles deserialization of method parameters in RMI calls is failing to properly deserialize instances of java.lang.Class. This occurs when I call an EJB methods remotely and not during any other serialization or deserialization (i.e.: I could not replicate this when serializing the object to a ByteArrayOutputStream and then deserializing from a ByteArrayInputStream -- I also tried with a FileOutputStream and FileInputStream and could not reproduce the behavior). The bug manifests itself when trying to deserialize java.lang.Integer.TYPE which represents the "int" primitive type as a java.lang.Class object. (I imagine the bug would also appear if deserializing Float.TYPE, Double.TYPE, or any other primitive TYPE constant). It appears that the deserialization is attempting to perform a Class.forName(String) on "int", which then fails with a message about there being no class loaders for class "int". The primitive types should be a special case in the deserialization method and looked up in a table. Like I said, this only occurs when I try to send Integer.TYPE over the wire to an EJB remote method call (not during deserialization from a ObjectInputStream based on a ByteArrayInputStream or FileInputStream) >From the stack trace it looks like the problem is actually in the org.jboss.invocation.MarshalledValueInputStream class. Any help with this matter would be great (especially info on how to fix it in my local 3.2.1 & 3.2.2 source code).
