Temurin-build: SAP JVM: testFailure: testStress(net.adoptopenjdk.test.concurrent.ConcurrentSkipListMapTest): null java.util.NoSuchElementException

[karianna]

From Volker at SAP

I'm not sure how to reproduce this error?

I've followed the instructions at https://github.com/AdoptOpenJDK/openjdk-systemtest and set JAVA_HOME to a SapMachine 10-ea+46-sapmachine-2 downloaded from https://sap.github.io/SapMachine/

I can successfully build the "openjdk-systemtest" (step 6 in the readme) but when I execute the tests (i.e. "make test") I get the following error:

testStarted : testStress(net.adoptopenjdk.test.concurrent.ConcurrentSkipListMapTest)

The same problem happens with a vanilla OpenJDK 10 as well.

Can you please advise how I can reproduce the problem?

Hi Volker,
The issue is seen during the building phase of system tests, where it tries to build the Mauve classes and fails as CORBA classes are not found. From your comment above, it appears that you were able to successfully build the sytstem-test source-- which means you have already gone past the point where the failure occurs (i.o.t., the test failure you reported is unrelated to the issue here).

Could you please post the build output that you saw while building systemtest with your SDK?

How is the SDK you used different than the SDK used in Adopt where the failure is seen? (We are using: https://ci.adoptopenjdk.net/job/openjdk10_sap_build_x86-64_linux/lastSuccessfulBuild/artifact/OpenJDK10_x64_Linux_201816032300.tar.gz).

This may be a test or systemtest issue in which case we'll shift it to that repo

[karianna]

Need to re-add SAP vms into the new build process/

[M-Davies]

@karianna Is this still an issue? I couldn't see any reference to SAP VM's in systemtest?

[smlambert]

We used to build and test it for jdk10 (and since its hotspot based vm, any tests that apply to our hotspot builds would also apply to sapmachine). I realize it doesn't answer your question, but thought it might help to give some history.

[M-Davies]

Used to? Do we not still?

[karianna]

Added to TSC agenda - not sure if we should continue building SAP

[smlambert]

"used to" - I believe only jdk10 was enabled, which is now retired.

[karianna]

I've reached out to Goetz.

@karianna any update on this?
