For new files, you usually take the copyright comment from a file nearby. All tests should use GPLv2 _**without** the "Classpath" exception_. The source code in `src` directory has the "Classpath" exception.

Here's a quote from [the jtreg tag spec](https://openjdk.org/jtreg/tag-spec.html#INFORMATIONAL_TAGS): “Use of this tag is now generally _discouraged_; information about the author and other contributions is generally better left to the source code management system for the test suite.”

With Git, your name will be associated with the commit, thus all the code you contribute, unless modified, will be attributed to you without the use of the `@author` tag.

> …but what's about copyright mention ?

You contribute the code [under the OCA](https://openjdk.org/guide/#sign-the-oca), “This agreement gives Oracle and you as a contributor joint copyright interests in the code. You will retain your copyright while also granting those rights to Oracle.”
