I'm looking at installing Java 7 as a requirement for a 3rd Party product

Anyone have any issues after installing Java 7? This is an IBM i 7.1
partition.

I'm on IBM i 7.2. GO LICPGM tells me this:

I set JAVA_HOME in my initial program because I have some older stuff I
want to use with Java 6. I created another user that does not set
JAVA_HOME, so here is the system default of JAVA *VERSION:

Java 6 and Java 7 can live side by side. You need to ask the 3rd party
vendor the recommended method of setting the JAVA_HOME they need.
