                 Summary: ObjectInputStream can't deserialize arrays from a
Sun stream
                 Project: classpath

                Severity: 3 - Normal
                  Status: None

             Open/Closed: Open
        Platform Version: None

    _______________________________________________________

Details:

If an array is written to an ObjectOutputStream on a Sun JVM, and that stream
is read by an ObjectInputStream on JikesRVM using Classpath 0.16, the read
fails due to a serialVersionUID mismatch.  

Only Sun-to-Classpath fails.  Classpath-to-Classpath and Classpath-to-Sun have
no problems.  

Attached are two files to demonstrate the problem:
% java SaveStrings
using file /tmp/test36196.tmp
% java Loader /tmp/test36196.tmp
read object [Ljava.lang.String;@1cd2e5f
% rvm Loader /tmp/test36196.tmp
Exception in thread "main": java.io.InvalidClassException: class
