@DanHeidinga I suspect this is a VM issue.

DanHeidinga · 2020-01-17T15:15:45Z

@sharon-wang Can you take a look at this?

sharon-wang · 2020-01-17T15:22:16Z

looking into this!

sharon-wang · 2020-01-20T18:57:19Z

Is this an intermittent issue? I have not been able to reproduce the failures so far.

Used the SHAs for the failed nightly above for a regular build and an XL build:

OpenJ9 - 859442d7f
OMR - 947946e7d
JCL - 8b47834a41c based on jdk-11.0.6+10)

I have run the following tests more than 100x each without any failures:

PLATFORM ppc64le_linux
BUILD_LIST system
TARGET MathLoadTest_bigdecimal_special_20
EXTRA_OPTIONS Mode610
JVM_OPTIONS -Xcompressedrefs -Xcompressedrefs -Xjit -Xgcpolicy:gencon

and

PLATFORM ppc64le_linux_xl
BUILD_LIST system
TARGET MathLoadTest_bigdecimal
JVM_OPTIONS -Xnocompressedrefs

pshipton · 2020-01-20T23:03:18Z

Is this an intermittent issue?

Yes it is. The complete failure history is recorded above, failed twice in the last 19 days.

sharon-wang · 2020-01-23T15:46:42Z

Have not reproduced this failure after 10000+ runs, but MathLoadTest_bigdecimal_0 did fail once on a different NPE which looks like: #4005

Continuing to run tests to try to reproduce the NPE on VMAccess.addPackageToList...

sharon-wang · 2020-01-29T20:06:30Z

Still unable to reproduce. Will keep an eye out for relevant failures to try to get a better idea of the root cause.

gacholio · 2020-02-02T20:54:44Z

The code in question is this:

	public void addPackageToList(java.lang.Class<?> newClass, ClassLoader loader) {
		java.lang.ClassLoader packageLoader = loader;
		if (Objects.isNull(packageLoader)) {
			packageLoader = ClassLoader.getSystemClassLoader();
		}
		packageLoader.addPackageToList(newClass);
	}

So this seems much more likely to be a JIT issue than a VM one.

gita-omr · 2020-02-03T16:19:40Z

Have we tried -Xint?

sharon-wang · 2020-02-03T16:27:03Z

Yes, however I haven't been able to reproduce the failure with or without -Xint

Note this originally occurred on ARM64, so it would seem not to be PPC-specific. The ARM JIT was based of the PPC one, so there may be an error duplicated between the codegens.
