I am not able to reproduce this locally or through grinder. It would be very helpful if we could get some coredumps for the failure from nightly build.

cathyzhyi picture cathyzhyi on 15 Apr 2020

@cathyzhyi pls provide the -Xdump options you want, and we can ask @Mesbah-Alam to help modify the test to include them.

@Mesbah-Alam could you help adding the following to the above a failing tests -Xdump:system+java:events=throw,filter=java/lang/NullPointerException#*java/lang/invoke/BruteArgumentMoverHandle.permuteArguments*

@pshipton is this one still happening or is it resolved in later builds?

I haven't seen anything since returning from vacation. @JasonFengJ9 have you seen this occur? Otherwise I'll close it.

@nbhuiyan could you please have a look?

I have been trying to reproduce this on Grinder as well as locally with Xdump options to obtain core dumps I can use for my investigation. Unfortunately, after 100 iterations on Grinder and almost 200 iterations locally of running the failed test target, I could not reproduce this failure. Are there any other recent builds where this happened?

nbhuiyan picture nbhuiyan on 23 Sep 2020

Are there any other recent builds where this happened?

I haven't seen it, but will report here if it shows up again.

pshipton picture pshipton on 23 Sep 2020

I haven't seen anything since returning from vacation. @JasonFengJ9 have you seen this occur? Otherwise I'll close it.

@pshipton no, I haven't seen it for a while, also tried TRSS search in recent builds and no hits either.

JasonFengJ9 picture JasonFengJ9 on 24 Sep 2020

Even though I'm not convinced the problem is resolved given https://github.com/eclipse/openj9/issues/8972#issuecomment-696829594, I'll close it. We can reopen if the problem is seen again.

I wonder if https://github.com/eclipse/openj9/issues/10759 is related.

pshipton picture pshipton on 1 Oct 2020

After at least 100 iterations of the failing target in each platform this failure surfaced in recently, I have been unable to reproduce it. I am not able to investigate further without being able to reproduce it and obtaining the core dumps. I will continue trying to reproduce this. I am not sure about how long it might take to achieve that.

nbhuiyan picture nbhuiyan on 1 Oct 2020

How about if we modify all the openjdk java/lang testing to have the -Xdump option you need, so the next time it occurs in the nightly builds there will be a core file.

pshipton picture pshipton on 1 Oct 2020

That will be fantastic! Please add the Xdump option in comment above for jdk_lang_j9.

nbhuiyan picture nbhuiyan on 2 Oct 2020

Created https://github.com/AdoptOpenJDK/openjdk-tests/pull/1989

Does the option change the JIT behavior? It's interesting we haven't seen the problem again in the system testing since the option was added (although we might have missing something while I was on vacation).

Does the option change the JIT behavior? It's interesting we haven't seen the problem again in the system testing since the option was added (although we might have missing something while I was on vacation).

I would be really surprised if that was the case. I did perform Grinder runs without the -Xdump option but could not reproduce the failure even then.

nbhuiyan picture nbhuiyan on 2 Oct 2020

Given the lack of progress I am moving this to the next release - we aren't likely to have a fix in time for the release.

There are NPEs related to InnerClassLambdaMetafactory.buildCallSite reported in https://github.com/eclipse/openj9/issues/10929

pshipton picture pshipton on 29 Oct 2020

Still no luck in reproducing this failure with the dump option set. Seems like the failures do not show up after setting up the -Xdump options. At this time we do not have a way to investigate this further and therefore this issue can not be resolved as part of 0.24.

nbhuiyan picture nbhuiyan on 4 Dec 2020

Given the inability to reproduce this problem with any form of diagnostic aids this is not going to be resolved for 0.24, hence moving this out to JDK16.

However, if the existing diagnostic procedures are not proving to be effective we will have to brainstorm more creative and bespoke approaches for 0.25.
