When would you enable strict Java mode in BeanShell?

Enable strict Java mode when you want BeanShell's convenience of skipping a formal compile step, but still want the same type-safety guarantees Java's compiler would normally enforce, such as when a script is significant or shared enough that catching type mistakes early is worth losing loose typing's convenience.

It's also useful as a validation step: running an existing script under strict Java mode can surface places where loose typing was silently papering over what would otherwise be type errors, which is valuable information before promoting a quick script into something more permanent.

It's generally not worth enabling for genuinely small, throwaway scripts where the whole point of reaching for BeanShell was the speed and convenience of not worrying about strict typing in the first place - strict mode is a deliberate tradeoff, not a default-on best practice for every script.
