Aleksandr commented on IGNITE-27098:
------------------------------------
Im ok with getting rid of org.apache.ignite.marshalling.MarshallingException if
we can do so (probably we're going to "break" the public API...).
If we can not remove this exception, let's inherit it from the `lang` one.
> Duplicate Marshaller exception class.

> Key: IGNITE-27098
> URL: https://issues.apache.org/jira/browse/IGNITE-27098
> Project: Ignite
> Issue Type: Improvement
> Components: compute ai3
> Reporter: Andrey Mashenkov
> Priority: Major
> Labels: ignite-3, tech-debt
> Fix For: 3.2
>
>
> Public API has two exception classes representing the same error.
> * `org.apache.ignite.lang.MarshallerException`
> * `org.apache.ignite.marshalling.MarshallingException`
> Let's deprecate the second one and make it child of the first one.
>
> Unfortunatelly there are bunch of issues
> * `ByteArrayMarshaller.unmarshal` throws MarshallingException however there
> should be `org.apache.ignite.marshalling.UnmarshallingException`, according
> to the logic of the whole PR where all of this stuff was added.
> * `org.apache.ignite.marshalling.UnsupportedObjectTypeMarshallingException`
> is not a part of marshaller exception hierarchy. Actually, none of them has
> meaningful parent.
> * `org.apache.ignite.marshalling.Marshaller` methods declare throwing a
> `UnsupportedObjectTypeMarshallingException`, however `MarshallerException`
> can be thrown as well.
> * `org.apache.ignite.marshalling.TupleMarshaller` interface is not used.
