Started a 1x grinder https://ci.eclipse.org/openj9/job/Grinder/718/ - passed on ub16-390-3

[pshipton]

2x grinders
https://ci.eclipse.org/openj9/job/Grinder/719 ub16-390-3 - failed only java/nio/charset/coders/BashStreams.java.BashStreams, which looks like a dup of
#8652

https://ci.eclipse.org/openj9/job/Grinder/720 ub16-390-1 - passed

@fjeremic fyi

[fjeremic]

Thought this could be related to #8992 but that looks to be a compile time crash and this is a runtime exception, so likely not related. @VermaSh could you take a look at this one given it is in the area related to Strings and we just merged the VSTRS fixes a few days ago. It could be related to that change.

[VermaSh]

@pshipton @jdekonin Could I get access to ub16-390-1

[pshipton]

Could I get access to ub16-390-1

Provided instructions via PM on Slack

[fjeremic]

Grinder shows a 1/30 failure rate:
https://ci.eclipse.org/openj9/job/Grinder/731

@VermaSh any updates?

[VermaSh]

@fjeremic Failures in that grinder seem to be agent related Agent communication error: java.io.EOFException; check console log for any additional details There don't seem to be any functional failures. Running them locally on ub16-390-1 machine to replicate failures

[fjeremic]

@VermaSh I don't think so. Look at the console output and search for "PASSED: 0 FAILED: 1", there is clearly a crash here which looks similar to the original one:

There are several more there with a final failure of a crash in GC due to what looks like a corrupt object.

[VermaSh]

ah dang, I thought Test Results section would show errors. Can you please launch a grinder using
OMR: git@github.com:VermaSh/omr.git branch: jdk_nio_0
openj9: git@github.com:VermaSh/openj9.git branch: jdk_nio_0 commit: ac8e0741103cca6fe77c61ed5e560cce2a91b1ed

[fjeremic]

There used to be a way to build personal builds off of branches, but I no longer see it here:
https://ci.eclipse.org/openj9/view/all/

That list is absolutely massive. I tried kicking off a "Build_Personal" however it is unintuitive what you actually have to specify in those textboxes:
https://ci.eclipse.org/openj9/view/Build_Personal/job/Build_JDK11_s390x_linux_Personal/

@pshipton do you might know of an easy way to get a build against the above repos/branches? We need to get a build so we can launch a grinder against it.

[pshipton]

@fjeremic it doesn't have the best name, but the "personal build" job you are looking for is https://ci.eclipse.org/openj9/view/Pipelines/job/Pipeline-Release-Build/
