Jukka Zitting commented on OAK-802:
-----------------------------------
The extra error details brought up something interesting:
{noformat}
testScoreColumn(org.apache.jackrabbit.test.api.query.SQLQueryLevel2Test):
org. apache.jackrabbit.oak.api.CommitFailedException: OakConstraint0001:
/testroot/node1[nt:unstructured]: No matching child node definition found
for child node node1 in any of the parent types [nt:base, nt:query]
{noformat}
I have no clue why the {{/testroot}} node would be of type {{nt:query}}, but
that's clearly triggering these test failures.

> Key: OAK-802
> URL: https://issues.apache.org/jira/browse/OAK-802
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: core, jcr
> Environment: happens at least on my laptop and on an ec2 m1.xlarge
> instance
> Reporter: Jukka Zitting
>
> Occasionally, like in 1% of the cases, I see a default {{mvn clean install
> -PintegrationTesting}} build fail with lots of type validation errors from
> the TCK. A typical example is:
> {noformat}
> testScoreColumn(org.apache.jackrabbit.test.api.query.SQLQueryLevel2Test)
> Time elapsed: 0.01 sec <<< ERROR!
> javax.jcr.nodetype.ConstraintViolationException:
> org.apache.jackrabbit.oak.api.CommitFailedException: OakConstraint0001:
> /testroot/node1: Incorrect node type of child node node1 [nt:unstructured]

> for the failsafe output of such an case.
> I've been able to reproduce the problem with a build loop like the following
> on my laptop and on a m1.xlarge ec2 instance (it didn't show up on a
> m1.medium instance):
> {code:none}
> for i in `seq 1 100`; do
> mvn clean install -PintegrationTesting > build$i.log 2>&1
> done
> {code}
