By default JSP is not thread safe.

I wouldn't phrase it like that. Many JSPs are thread-safe without the developer doing anything to make them so - simply because they do not use shared mutable state. However, I'd agree to a statement like "Any given arbitrary JSP can not be considered thread-safe until it is inspected and found to be so (or made so)."

Indeed, if JSPs are written to modern standards (in other words, no scriptlets and no Java code within them), it's rather hard to make them non-thread-safe. Modifying properties willy-nilly on shared scoped variables in session and application context is about the only place you could get yourself into trouble.
