Putting it very bluntly in my opinion it is crazy to intentionally pick a very old version
of a library because you are stuck on an ancient version of java.
Generally migrating from Java 1.4 to a later version should be painless - there's a
risk of issues with subtle changes in how java handled strings buffers but most people
wouldn't hit that. Generally it should be a case of (optionally) recompiling and
running it in an up to date JVM and doing some regression testing.
I'd strongly recommend doing this before or as part of your rules engine work
(afterall you're going to have to do a load of regression testing anyway).
If you are leaving the migration till later remember java 6 only has 13 months of life
left in it and you'd really be wanting to migrate to java 7!

Thanks for the reply.
Actually I have to work on an Application that is based on Java 1.4 and there
haven't been any major changes in the code, currently business logic is
managed through Java code only. But now we are trying to have a rule
engine for the purpose. There will be a migration to Java 6 but not in the near
future.

Any reason why you are still on java 1.4?
You are using a java version that is now 3 major versions out of date and that
hasn't been supported by sun/oracle for the last 3 years!
It's the equivalent of still using windows 98!
