I suggest that you carefully compare the "bugs fixed" sections of the respective release notes for the respective versions.

Note that the release date for the 1.4.2_06 version is 2004-12-10 (according to the release notes), while the IBM version name is "20090307" which implies that it was built ~5 years later. While there is no guarantee that the IBM version has tracked all of the fixes to that date, it is a fair assumption that they will have (at least) tracked the security-related patches.

Reason why I posted this because when I tried to do some deployment to server from command line, I am having few issues so wonder this could be difference in java versions.

Possibly, but (IMO) it is more likely that the problem is nothing to do with the version of Java. Either way, I think that an enumeration of the differences is unlikely to help you isolate your problem.

I suggest that you ask a new Question in which you describe your actual problems. We may or may not be able to help ... but I think your chance of success is greater than with your current approach.

They are very different from the implementation point of view as the first one is from Sun and the second from IBM. Since they are from different vendors, the patch level means nothing (the _06 on the Sun JDK).

From a behaviour point of view, they should be the same. Having said that, I remember some issues in the past with the IBM jdk, in which it would perform really poorly.

If you want to use IBM's version of java, you can get it from here.
