----------------------------------------
Assignee: Steve Lawrence
> Need better error message when missing plugin
> ---------------------------------------------
>
> Key: DAFFODIL-2915
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2915
> Project: Daffodil
> Issue Type: Bug
> Components: Diagnostics
> Affects Versions: 3.8.0
> Reporter: Josh Adams
> Assignee: Steve Lawrence
> Priority: Minor
>
> Ran into an issue where a saved parser was relying on a plugin for Daffodil.
> Note that this plugin needs to be present when both compiling and running the
> schema.
> When attempting to run the saved parser without the plugin being present on
> the classpath, I would get the following stack trace:
> java.lang.ClassCastException: cannot assign instance of
> scala.collection.immutable.List$SerializationProxy to field
> org.apache.daffodil.runtime1.processors.ModelGroupRuntimeData.groupMembers of
> type scala.collection.Seq in instance of
> org.apache.daffodil.runtime1.processors.SequenceRuntimeData

> like this could be baked into the saved parser flie.
