[eclipselink-dev] Bug 387491 - Three JUnitJPQLDateTimeTestSuite tests fa

[Andrei Ilitchev <andrei.ilitchev@xxxxxxxxxx>]

Checked the updated patch into both trunk (2.5) and 2.4 streams.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=387491

Updating this bug fix as requested by James.
Truncating every sql.Date before passing it to Statement.setDate would 
cause some performance deterioration, therefore instead of automatically 
enabling it, data truncation is disabled by default, could be explicitly 
enabled by the user by calling: oracle9Platform.setShouldTruncateDate(true);

Also made date truncation a bit more efficient: only one calendar is 
created and milliseconds are ignored (i.e. date without hours, minutes 
and seconds, but with milliseconds would not be truncated) - 12.1 driver 
still truncates milliseconds.

Thanks,
Andrei
