Michael Bouschen updated JDO-206:
---------------------------------
Attachment: JDO-206.patch2
Attached you find a new patch (JDO-206.patch2) for review.
The patch changes the schema for derby and uses the coumn type REAL for all
float fields. With this change test NotEquals succeeds. I also fixed table
PrimitiveTypes and changes the column type of doubleNull and doubleNotNull to
DOUBLE.
Please note, the localSetUp change from JDO-206.patch is already checked in.

> The current TCK test (carried over from JDO 1.0) for NotEquals, uses !=
> operator on floating point numbers. This is not a good practice, and is
> unreliable. Its probably the case that the Equals test uses == on the same
> content, which also is not a good idea (as noted in the latest spec). These
> tests need reviewing and a reliable alternate strategy adopting
