Thank you for reading this post and attempting to help me.
I am being tasked with a project to migrate a application that was developed on JDK 1.4 to JDK 1.6, the application is not going to go through any functional change. I went about upgrading my Eclipse JRE version to 1.6 and one thing that popped was "Enum" issue and I have fixed it. Now the code is compiling and I am able to execute the application. The application is going go through regression testing, before that I would like to do a test using some plug-in or tool that would help me to identify any potential JRE 1.6 run-time issues.
If you could point me to a tool or plug-in that I could use to identify potential run time issues related JDK / JRE 1.6.

I never heard of such a thing. I suggest reading the release notes and bug fix notes on what they changed going from the old version to the new version for some ideas.
Also, in addition to errors, look at warnings that Eclpise produces. You don't strictly need to fix them (their just warnings), but its a good idea since they hide real issues in the code where warnings suggest the original coder may have done something that isn't logically too complete. I think a lot of warnings may have to do with generics.
You may also want to look at deprecation warnings (again, you don't strictly need to fix them, but some release of java in the future will eventually not allow you to compile those old deprecated objects).
Lastly, your other systems may be in the process of being upgraded too (such as the database, server, etc) which may have some impact (example: you might consider updating your JDBC driver, and for the server, the nature of its xml configuration file for the JDBC driver may have changed).
