We have a slowdown [JDK-8350573](https://bugs.openjdk.org/browse/JDK-8350573) of the `java/beans/XMLDecoder/8028054/TestMethodFinder.java` test

The possible test would be to set a timeout for it, but is depends on the hardware:

> On my test machine the test runtime goes from ~ 40s (hash of the change before [JDK-8344891](https://bugs.openjdk.org/browse/JDK-8344891)) to ~ 1:40 ([JDK-8344891](https://bugs.openjdk.org/browse/JDK-8344891)) .

> Locally on my M1 Macbook pro this test runs in ~4 seconds before and in ~28 seconds after [JDK-8344891](https://bugs.openjdk.org/browse/JDK-8344891) change.

So I believe it would be better to track anomalies by test execution time history in the CI.
