> If you pre-compile a schema to a binary file, then try to parse data with it, without setting up the DAFFODIL_CLASSPATH to provide access to a layer plugin, you get an abort during deserialization (i.e., reload) of the stored parser. 
> The workaround is of course just setup the DAFFODIL_CLASSPATH for running the CLI the same as when the parser was compiled and saved.
