This test "Checks PLAB statistics on evacuation failure", but the log decorators used are "-Xlog:gc=debug,gc+phases=trace". Therefore, the logs contain no PLAB related info. However, all checks in this test still pass.

The essense of all checks is the following, when `logItems` is empty, this method becomes a no-op, skipping all checks.

```
    private static void checkValues(Map<Long, PlabInfo> logItems, String errorMessage, boolean expectZero) {
        logItems.entrySet()
                .forEach(...);
    }
```
