---------------------------------

             Summary: Occasional type validation errors in TCK setup
                 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]
	at org.apache.jackrabbit.oak.jcr.delegate.SessionDelegate.newRepositoryException(SessionDelegate.java:331)
	at org.apache.jackrabbit.oak.jcr.delegate.SessionDelegate.save(SessionDelegate.java:196)
	at org.apache.jackrabbit.oak.jcr.SessionImpl.save(SessionImpl.java:369)
	at org.apache.jackrabbit.test.api.query.AbstractQueryLevel2Test.setUpFullTextTest(AbstractQueryLevel2Test.java:45)
	at org.apache.jackrabbit.test.api.query.SQLQueryLevel2Test.testScoreColumn(SQLQueryLevel2Test.java:41)
{noformat}

See https://www.dropbox.com/s/57cps6ys0etd9an/org.apache.jackrabbit.oak.jcr.tck.QueryIT.txt 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:sh}
for i in `seq 1 100`; do
    mvn clean install -PintegrationTesting > build$1.log 2>&1
done
{code}
