>
> Key: DIRMINA-822
> URL: https://issues.apache.org/jira/browse/DIRMINA-822
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.2
> Reporter: Ulrich Kreher
> Fix For: 2.0.3
>
> Attachments: AbstractIoBuffer.patch
>
>
> AbstractIoBuffer uses ObjectStreamClass.lookup(Class) which returns null for classes that do not implement Serializable. This in turn leads to a NullPointerException a few lines below in resolveClass(ObjectStreamClass) where the ObjectStreamClass-parameter is null.
> Deserialising a non-serialisable class is completely legal, instances of such a class will already fail to serialise so they will never get to deserialisation.
> Using ObjectStreamClass.lookupAny(Class) will solve this issue, but it is not available before Java 6.
