java-repl and Jshell are both repls. Here is the definition of a repl per wikipedia:

"A read–eval–print loop (REPL), also known as an interactive toplevel or language shell, is a simple, interactive computer programming environment that takes single user inputs (i.e. single expressions), evaluates them, and returns the result to the user;"

Just as sublime text editor workspaces could both be considered text editors, java-repl and Jshell are both REPLs. It's my understanding that Jshell has a bunch of new bells and whistles (like tab complete -- yay!) and that is why Craig choose to demonstrate it in newer videos.
