Emmanuel Lecharny commented on DIRMINA-822:
-------------------------------------------
Ok, someone already proposed a patch 3 years ago, but it was for MINA 1.1.7,
which is considered as dead wood, thus it was never fixed in MINA 2 too.
I have applied the patch provided in DIRMINA-627 :
http://svn.apache.org/viewvc?rev=1082736&view=rev
I'll build some jars and put them on my home page for those who want to test it.
> Deserialising classes that do not implement Serializable fails
> --------------------------------------------------------------
>
> 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
> 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.
