Not all Tag libraries should be imported

Software ResiliencyProgramming Best Practices

Why you should care

A tag library defines a collection of custom actions. The tags can be used directly by developers in manually coding a JSP page, or automatically by Java development tools. A tag library must be portable between different JSP container implementations.
If the tag library is not utilized, the custom actions are not defined resulting in specification issues

Business Impacts

Having more tag libraries than necessary is risky for the code. It is best to only have tag libraries that are used so that the code can be more productive.

Production Risk

How we detect

This code insight establishes that only tag libraries that are being used in a page should be imported
