org.apache.derby.iapi.sql.execute.ExecutionFactory
This is the factory for creating a factories needed by execution per connection, and the context to hold them.
There is expected to be one of these configured per database.
If a factory is needed outside of execution (say, data dictionary or compilation), then it belongs in the LanguageConnectionContext. @see org.apache.derby.iapi.sql.conn.LanguageConnectionContext


    // push the context that defines our class factory
    pushClassFactoryContext(cm, lcf.getClassFactory());


    // we also need to push an execution context.
    ExecutionFactory ef = lcf.getExecutionFactory();


    ef.newExecutionContext(cm);
    //
    //Initialize our language connection context. Note: This is
    //a bit of a hack. Unfortunately, we can't initialize this
    //when we push it. We first must push a few more contexts. 
    lctx.initialize();
