Subject [jira] Updated: (HARMONY-91) Serialization: fails to deserialize stream in case of added class to hierarchy
Date Tue, 14 Feb 2006 16:13:10 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-91?page=all ]

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.
