Production version of SDK : definition directly from SUN

Hi all, I quote here the answer I received here from SUN to my question, which is one that is often asked here I think. Their answer is crystal clear.
Hope this helps

Hello Stephane,
I received your inquiry from my customer service team and discussed it with one
of my Java Subject Matter Experts who helped design the certification exam.
She stated we view a production version as any version that was downloadable
directly from java.sun.com, as long as it wasn't an "Early Access" and/or BETA
release, or one of the older "developer releases" (which was an alternate
version of the JDK, also available from java.sun.com, but we don't do that any
longer).
This version (1.4.0-b92) should be fine. The '-b92' refers to a particular
build, so as long as you are using what was a full release (FCS) then there will
be no problem. Currently there is both a 1.4.0 and 1.4.1 available as production
versions, both of which are acceptable for the assignment.
The real key is to remember how you obtained the J2SDK, to ensure that it wasn't
a pre-release/early access/beta version that you downloaded. The risk with a
beta version is that something you compile and run on a beta version might work,
and then fail to work on a production version that we use to test it on.
Hope this is helpful.

I used JDK 1.4.0 and JDK1.4.1 but now in my assignment, I am using jdk1.3.1_02 as it's javadoc API is well knwown to me. I think that'll be enough. But if I would have eough time, I would use JDK1.4.1 as it would a nice learning curve....
