Since jtreg 7.5.2 folders created by @TempDir annotations use a generic "junit-2304958203948" name. This makes it hard to connect them to the current test (method) being run.

The folder name should use information available at the runtime of a JUnit test to compose a better name. By using, for example, the name of the test method, the parameters, the current repetition index, maybe even current arguments.
