Hi Michelle,
looks much better now. Not sure what you're expecting from me on this one. T
he error is

rk.AssertionFailedError: Assertion (TestArrayCollections) failed:

so we have a series of floating point numbers that were stored in the RDBMS 
and when retrieved have a different precision. We know that RDBMS don't pres
erve the precision exactly (as shown on other TCK tests). Does the TCK not h
ave a method to perform rou
nding so that the numbers can be compared at the precision of the value that
 was input ? With all of the differences above, if the actual value is round
ed up or down (depending on the number) they would be identical and the test
 would pass.
