TableName not serializable

Description

I'm not sure how, but sometimes an EmbedSQLException can hold on to a TableName. Since TableName is not serializable we can not ship derby exceptions to remote clients. It is common usage for EJB applications to simply pass exceptions through to remote clients.

This is the exception I get when I try to serialize an EmbededSQLException... sorry this is not much help on what is causing EmbededSQLException to hold onto a table name but Java Serialization doesn't throw nice exceptions.
