What do you use it for?
It's such a complex language brimming with idiosyncrasies that I'd be inclined to really test anyone claiming to be a master. The standard is one thing, then there's the compiler you're using...

Also a programming language is not used alone and C++ standard library is quite tiny when compared to Java's standard library.
Even parts of C++ that are "normal user" features can be remarkably tricky. I know tons of C++ programmers who I'd happily trust to write code for me who would fall flat on their faces if asked to explain some detail of what std::forward does with an rvalue reference parameter bound to an lvalue argument.
There's a reason why a very common recommendation is to pick a subset of C++ and stick to it, and I've never heard of such a recommendation for any other language (outside of perhaps for portability reasons).
That is true.
I can also remember other ones like differences between auto and decltype, or between auto and template parameter deduction across language revisions.
However, Java puzzles like the ones presented at Java ONE, or .NET changes in how native error handling changed on .NET 4.0, among many other examples, are also interesting as quiz questions.
std::move?
