LogRecordThreadIdTest previously used TestNG @BeforeTest, which runs before each @test method, so each test started with freshly constructed LogRecord instances. With JUnit @BeforeAll + static fields, the same instances are reused. The assertions still look safe because each test overwrites the state it cares about, but could you confirm this was intentional? If you want to preserve the old “fresh records per test” behavior, @beforeeach (possibly with non-static fields) would be closer to TestNG.

As far as I understand @BeforeTest means that the method will be run before any test in the test group. If there is no test group, the test group is the class. Which means that BeforeAll/BeforeTest/BeforeClass are all equivalent here. That said there's no real reason to use a setup method here. I simply removed it.

record = new LogRecord(Level.INFO, "record");
