Avoid Vector & Hashtable

For all developers; please avoid the use of Vector & Hashtable in most cases. Since they are all synchronized, which is usually not needed, they are much slower then the various List & Map implementations.


a place to put such things

I think we should have a dedicated place to put such recommendations.


Developer's Guide

Maybe the Developer's Guide should contain a page called 'Coding Coventions' or so that might contain such recommondations.
