Steve Lawrence updated DAFFODIL-2266:
-------------------------------------
    Priority: Minor  (was: Major)

> Daffodil does not validate compatability with pre-compiled parsers
> ------------------------------------------------------------------

>                 Key: DAFFODIL-2266
>                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2266
>             Project: Daffodil
>          Issue Type: Bug
>          Components: Middle "End"
>    Affects Versions: 2.5.0
>            Reporter: Brandon Sloane
>            Priority: Minor

> In general, we do not claim to support untrusted input as pre-compiled parsers, so not validating pre-compiled parsers is reasonable.
> However, a common mistake users are likely to make is using a parser compiled with a different version of Daffodil. While this is not supported, we do not fail gracefully, instead throwing the below unhandled exception. We should instead detect this case, and issue a user-friendly error indicating the problem.
