Stepan Mishura updated HARMONY-91:
----------------------------------

    Attachment: fixHarmony91.txt

The patch contains a fix and a minimized test case: all serialization tests from security2 passed.
Also I removed 2 tests from Harmony exclude list and, if Tim don't mind (I don't smoke at all :-)), I added CLASSPATH onto the bootclasspath for luni -need bcprov there to run the test.

> According to the serialization spec. adding classes is compatible change and shouldn't affect serialization. The current implementation of java.io.ObjectInputStream class fails to deserialize stream (reconstitute an object) in this case. Particularly, it fails when super class for added class contains serialized fields.
> The following tests from security2 fail because of this bug:
> 1) javax/security/auth/login/serialization/SerAccountExpiredExceptionTest.java (added javax.security.auth.login.AccountException in Java Spec 5.0 as super class)   
> 2) javax/security/auth/login/serialization/SerCredentialExpiredExceptionTest.java (added javax.security.auth.login.CredentialException in Java Spec 5.0 as super class)   
> I've create serial form by hands to provide minimized test case with dynamic generation of required serialization byte array (i.e. serialization form now is immune for test class rename) but it is still quite long. So I'll add a test case to reproduce the failure as a patch for this JIRA bug.
