testReadCommitted(org.apache.derbyTesting.functionTests.tests.store.UpdateLocksTest)junit.framework.AssertionFailedError:
Missing rows in ResultSet

--------------------------------------------------------------------
You're right of course.
This was because I looked at the stack trace of the original error, which shows this:
------------
testReadCommitted(org.apache.derbyTesting.functionTests.tests.store.UpdateLocksTest)junit.framework.AssertionFailedError: Missing rows in ResultSet
at org.apache.derbyTesting.junit.JDBC.assertUnorderedResultSet(JDBC.java:1349)
at org.apache.derbyTesting.junit.JDBC.assertUnorderedResultSet(JDBC.java:1285)
at org.apache.derbyTesting.functionTests.tests.store.UpdateLocksTest.updateBtreeSetLocks(UpdateLocksTest.java:6764)
-------------
So I assumed I had to put the call for wait_for_post_commit *before* the assertUnorderedResultSet call on line 6764.
The delete-commit it would affect is then not the delete call right before ((original file line 6760/6761): s.executeUpdate("delete from a where a = 2 or a = 4 or a = 6");)
Because, as you say, there's no commit for that one yet.
Instead it would be for the earlier delete (original file line 6689/6690):
s.executeUpdate(
"delete from a where a = 4");
which got committed on line (again, original file numbers:) 6732.
Still, there's no good explanation for the placing of the other wait_for_commit calls. I will make a new patch that does the call after the commit belonging to each delete - and after the commit following each deleteRow() call.
