What is strict Java mode in BeanShell?

Strict Java mode is a setting, enabled via setStrictJava(true) on an Interpreter or the equivalent script command, that disables BeanShell's loose-typing conveniences and requires scripts to follow standard Java's type rules exactly, like plain Java source would.

With it enabled, a script that tries to assign a value to an undeclared variable, the way loosely-typed BeanShell normally allows, will fail instead, since the interpreter now enforces the same declaration rules Java's compiler would.

This is useful when a team wants BeanShell's convenience of not needing a full class and build step, while still catching the kind of type-related mistakes strict typing would normally catch, rather than only discovering them at runtime.
