Recommended updating Java source from 1.4.2 to 1.6.0_10? (skipping 1.5)

Our desktop only for work uses JDK 1.4.2 so far (also 1.4.2 JRE comes with the product). I am trying to convince the management to allow us to switch to a newer version in order to get productivity, API / features and developer benefits.

Since 1.5 has reached the EOL transition, I am thinking of upgrading to 1.6.0_10 directly (Update 10 is chosen as important). From a code point of view, all compilation errors are simply the names of variables under the name enumthat I renamed, and the product works fine.

Question:

  • Is this update / penalty recommended, i.e. a 1.5 pass? are there any tricks
  • If so, should I upgrade to 1.6u10 or the latest 1.6 available?

thanks

I would say that if you are going to upgrade, then go to any last update. In fact, you can get some free profit with 1.6, I know that some JVM improvements have been made since 1.4.

In general, Java is pretty good in reverse.

If you need to find out what has changed on the Java platform from 1.4 to 6, there is a list of changes that Sun has indicated for each version:
