Hi Martin,

It's easy enough to get the test to pass by delambdafication.
But we may not want to fix the test because it's not clear whether
it's a jdk lambda bug or not, and we don't sweep bugs under the rug.
Maybe instead of a "tier2" bucket we really want a "test found a bug
that's not yet fixed" bucket?
Well, we have a bug for the test failure in JDK-8150014 and now this bug
to demote the test from tier 1 to tier 2. The planned snapshot for the
next promoted build is next Monday. I don't think we should knowingly
let an intermittent tier 1 test failure escape to a promoted build.
Alternatives to achieve that goal include:
1) Demoting the test to tier 2 temporarily (If the cause of the problem
is known, this is less helpful than if more data needed to be gathered.)
2) Putting the test on the problem list so it doesn't get run at all.
3) Changing the test so that is passes (delambdafication as you've
suggested).
4) Changing / reverting the other libs code which triggered this failure.
The closest approach to "test found a bug that's not yet fixed" is
putting the test on the problem list, option 2). I'm happy to do either
1) or 2) under JDK-8150206 as an investigation into 3) or 4) proceeds
over a longer period of time. I just don't think we should leave the
test in its current flaky state for the next promotion.
Thanks,
-Joe

Hello,
Right now, we are seeing some cross-platform intermittent failures of
java/lang/invoke/LFCaching/LFMultiThreadCachingTest.java
as noted in bug JDK-8150014. Until that test instability is resolved, the
test should be demoted from tier 1 to tier 2.
Please see the patch below.
(Circumstantial evidence points to the changes in JDK-8145485 being
involved.)
