It is likely it is the same as #9046.

I ran this test 10 times manually on cent7-aarch64-1, and saw no failures.

https://ci.adoptopenjdk.net/view/Test_grinder/job/Grinder/2725 grinder got aborted early but theres still over 50% failures in there.

It was on test-packet-armv8-ubuntu-16-04 which is also might be causing another test to fail intermittently #9048

Where can I find the following OpenJ9 binary used in the grinder test?

openjdk version "11.0.7" 2020-04-14
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.7+9-202004012325)
Eclipse OpenJ9 VM AdoptOpenJDK (build master-bd765361f, JRE 11 Linux aarch64-64-Bit 20200401_136 (JIT enabled, AOT enabled)
OpenJ9   - bd765361f
OMR      - 0ecff81ea
JCL      - 34c3dd7d55 based on jdk-11.0.7+9)

The grinder just downloaded the latest nightly build from Adopt at the time.

Looks like its a tag from 01/04/2020 which should be still available at https://adoptopenjdk.net/nightly.html?variant=openjdk11&jvmVariant=openj9.

This one: https://github.com/AdoptOpenJDK/openjdk11-binaries/releases/download/jdk11u-2020-04-02-05-13/OpenJDK11U-testimage_aarch64_linux_openj9_2020-04-01-23-32.tar.gz

Thanks.
The link above is a testimage. I downloaded https://github.com/AdoptOpenJDK/openjdk11-binaries/releases/download/jdk11u-2020-04-01-14-28/OpenJDK11U-jdk_aarch64_linux_openj9_2020-04-01-14-28.tar.gz instead.

Assuming it is the same failure with SSLException as that in #9046, see my comment #9046 (comment) .

Repeat of this: https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_sanity.system_aarch64_linux/145/tapResults/

[knn-k]

Those crashes in libj9jit29.so are caused by getJittedBodyInfoFromPC() returning a NULL.
It is a known problem as #9574.

I am closing this as a duplicate of #9046.
