Hello Volkan, within the JDK build, we launch these jtreg tests with assertions enabled by default. However, from what I see in the build files, that's configurable. So it may not always be the case that assertions are enabled for these tests.

Furthermore, I don't remember seeing `assert` being used within the test code to verify the test expectations. So I think it would be better to do a conditional check here and explicitly throw a `AssertionError` if that check fails, like we do in some other places of this test.
