DescriptionDalLockingTest randomly fails. It seems it has some race condition.
Steps To Reproduce1. Execute DalLockingTest
2. Sometimes you get:

Expected: is <[T2, T1]>
     but: was <[T1, T2]>

fixes BUG-46159: unstable DalLockingTest.lockedObjectShouldAllowChildrenCreation

This tests executes 2 threads:

  - T1: acquires a lock on an AlertRule and keeps running for a while
    (200ms)
  - T2: is executed after the lock is aquiered and inserts a recipient
    for the rule with the lock

The tests asserts T2 completes before than T1, ensuring in PG the lock
is a FOR UPDATE NO KEY which allows insertions in child tables even
there is a lock in the parent. It assumes T2 completes faster than the
200ms T1 waits after the lock is acquired.

In certain cases, it is possible T2 to take more than 200ms to do
complete the instertion. In these cases T1 will finish before T2 making
the test fail.

This commit fixes the problem by removing the fixed 200ms wait in T1
replacing it with a latch to wait for T2 to complete (or fail if it
takes more than 10s, which never should be the case).

On top:
  - It adds some timing information to the logs
  - fixes a typo in waitUntil method name

Reopening:

Previous fix has been backed out because finally it was more unstable than before.

Reducing the number of cores executing the test, it is easier to reproduce:

  taskset -c 0 ant run.test -Dtest=org.openbravo.test.dal.DalLockingTest
