Exclude via adoptium/aqa-tests#6726

@JasonFengJ9 is this still failing in the latest runs?

[JasonFengJ9]

Launched 50x grinder with un-excluded test - still in progress, 10+ timeout occurred.

[JasonFengJ9]

The grinder #22936 (comment) is still in progress, 10+ timeout has been reproduced, and no pass run yet.
Edit: this seems a consistent timeout, all finished KlassInit.java tests timed out.

@tajila the latest build still has the timeout issue.
