Is it very difficulty, to write a test, to find out?

I've seen the same suggestion to a number of questions on this board, "Try it and see".

However, there are things you can do in most languages that are unsupported but still work. Along comes a new SDK release, or just a different execution path, and the same thing doesn't work.

In this case, a closed file can be reused if none of the pieces have been garbage collected. This question is whether you are allowed by the spec to reopen a closed file.

Is there a guarantee in Java that all illegal usages always result in a compile or execution error?
