[jdom-interest] java 1.1 exception

[Michael Salmon]

hi folks,
    curious if anyone has seen an error similar to this when deserializing
a Document in java 1.1.

java.io.InvalidClassException: com.sun.java.util.collections.AbstractList; IllegalAccessException
at java.io.ObjectInputStream.inputObject(ObjectInputStream.java:945)
at java.io.ObjectInputStream.readObject(ObjectInputStream.java:284)
at java.io.ObjectInputStream.defaultReadObject(ObjectInputStream.java:403)
at java.io.ObjectInputStream.inputObject(ObjectInputStream.java:985)
* at java.io.ObjectInputStream.readObject(ObjectInputStream.java:284)
at TestApplet.run(TestApplet.java:32)
at java.lang.Thread.run(Thread.java:504)

    I have tested that the serialized object stream im reading from is valid
with a newer jdk and in TestApplet that the exception is thrown from, the
objectinputstream object is valid when I read from it. 
    I am looking at classes in jdom that extend collections, ContentList, 
AttributeList and changed the private classes to public and did the same for
their inner-classes. That did not fix it though.
    I also tried building jdom with ant, target=1.1, rebuilding my app with
the changed jdom and rewriting my serialized object with the new program. 

thanks,
    ms
