------------------------------------
Summary: 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
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

It took quite a while to figure out what the problem was. Don't know if it
would be possible or reasonable, but it would be nice if any dependencies like
this could be baked into the saved parser flie.
