Subject [jira] Commented: (JDO-263) TestArrayCollections: Field "org.apache.jdo.tck.pc.fieldtypes.ArrayCollections.ArrayOfObject1" is declared as a reference type (interface/Object) but no implementation classes of "java.lang.Object" have been found!

Andy Jefferson commented on JDO-263:

You say that your patch changes the results to those you show in 04 Jan. Well if I round the
numbers (that current SVN gives and that I quoted) to the same precision as what was "expected"
I get the exact same number as the expected. I only have to look at the numbers to do that.
For example if I take  64564645656.78656768798828125 and round it to the same precision as
the expected (64564645656.78657 - i.e 5 decimal places) then I get 64564645656.78657. Where
does your number come from ?

Why it is different from other tests? I've no idea. I do know that storage of and retrieval
of large floating point numbers is unreliable - see the issue about "LessThanEquals" and about
Derby storing things in a seemingly odd way. The only difference here is that you have a serialised
array of large floating point numbers, as opposed to a single column with a large floating
point number in it. Consequently we have introduced serialisation, and arrays
Why does the serialised BigDecimal fail ? see above. It is serialised.

I still fail to see what JPOX is expected to do when the underlying datastore doesnt store
floating points in a reliable way.
