@zl-wang can someone take a look at this pls.

I'm assuming the problem is going to affect 0.57 given the date of the original report.

this looks like a dup of what @IBMJimmyk opened up for occasional jbb2015 crash: on decReferenceCount() as well. he will take (is taking) care of it

This looks just like the problem I ran into a few days ago with SpecJBB2015 on JDK11 PPCLE Linux. Internal grinder: https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder_iteration_1/6579/

So I'm already looking at the overall problem although I've only recently started. I'll also look at the other test cases as well since they might be easier to work with than SpecJbb.

IBMJimmyk avatar Dec 10 '25 20:12 IBMJimmyk

I have been trying to run Grinders for the SpecJBB version of the problem. But, so far I have not been able to reproduce the failure with the following options:

-XX:+MergeCompilerOptions '-Xjit:{*Interconnect*Downlink.acceptRequest*}(tracefull,log=acceptRequest.log),verbose,vlog=acceptRequest.vlog'

I also have SpecJBB running on a local setup, but due to the low failure rate I haven't been able to reproduce the failure there either.

In regards to the MiniMix version of the problem. I've been having problem passing in the Xjit options I want to the grinder. I think this might be because it's a System test.

The options I want are:

-XX:+MergeCompilerOptions -Xjit:{*gnu*testlet*java*text*SimpleDateFormat*applyPattern*test*}(tracefull,log=patternTest.log),verbose,vlog=patternTest.vlog

However, I can't seem to figure out which characters need to be escaped. I've tried following the examples here: https://github.com/adoptium/aqa-tests/wiki/How-to-Run-a-Grinder-Build-on-Jenkins#testOptions But, I still get errors complaining about invalid JIT options.

IBMJimmyk avatar Dec 11 '25 18:12 IBMJimmyk

I talked to Henry and he was able to figure out the escape pattern needed:

-XX:+MergeCompilerOptions -Xjit:\\{*gnu*testlet*java*text*SimpleDateFormat*applyPattern*test*\\}\\(tracefull,log=patternTest.log\\),verbose,vlog=patternTest.vlog

So I will be trying that out as well.

IBMJimmyk avatar Dec 11 '25 22:12 IBMJimmyk

I was able to run some longer grinders overnight.

I was trying to run SpecJBB with a JDK21 ppcle Linux build but wasn't able to reproduce the failure even without any special options. Internal grinder passed 40/40 times: https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56839/

Since the original SpecJBB failure was on JDK11, I tried switching to JDK11 ppcle Linux. Internal grinder failed 2/100 times (also no special options): https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56847/

So now I tried adding my Xjit option in to the JDK11 build:

-XX:+MergeCompilerOptions '-Xjit:{*Interconnect*Downlink.acceptRequest*}(tracefull,log=acceptRequest.log),verbose,vlog=acceptRequest.vlog'

Internal grinder passes 150/150 https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56852/

So failure rate is low and gets lower when I add trace options. As a result, trying from the SpecJBB side might not work too well.

My next step is trying to get a failure with MiniMix. It takes around 3 hours to run but seemed to fail more often.

IBMJimmyk avatar Dec 12 '25 15:12 IBMJimmyk

So failure rate is low and gets lower when I add trace options

Something else to consider trying instead of traceFull is traceOptTrees={*} - that will dump trees following each optimization that matches the specified pattern, either by name or opt index. It might result in lower overhead than the full blown traceFull.

hzongaro avatar Dec 12 '25 17:12 hzongaro

MiniMix also has the problem go away if the method is being traced.

Internal grinder with no special options fails 5/10 times: https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56873/

EXTRA_OPTIONS: -XX:+MergeCompilerOptions -Xjit:\\{*gnu*testlet*java*text*SimpleDateFormat*applyPattern*test*\\}\\{hot\\}\\(tracefull,log=patternTest.log\\)

https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56880/ Passes 20/20.

That's one method at only one hotness level.

I will see if reducing the amount of logging will help.

IBMJimmyk avatar Dec 14 '25 20:12 IBMJimmyk

I was able to reproduce the failure with traceCG:

EXTRA_OPTIONS: -XX:+MergeCompilerOptions -Xjit:\\{*gnu*testlet*java*text*SimpleDateFormat*applyPattern*test*\\}\\{hot\\}\\(traceCG,log=patternTest.log\\)

https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56892/

I also tried traceOptTrees={*} but got unexpected failures:

EXTRA_OPTIONS: -XX:+MergeCompilerOptions -Xjit:\\{*gnu*testlet*java*text*SimpleDateFormat*applyPattern*test*\\}\\{hot\\}\\(traceOptTrees=\\{*\\},log=patternTest.log\\)

https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/56893/

Unfortunately, I'm feeling a little under the weather right now so I wasn't able to take a deeper dive.
