> 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
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 3.2.0
>
>
> 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.
