Java 6 32-bit is the "expected" default - this link lists the available versions at the various releases -

The link for 7.1 on that page ( ) lists the hierarchy that the system uses to determine the default - and that default depends on what is installed. It doesn't depend on the order of installation.

We recently upgraded to 7.1 and during the install we selected to only install the 64-bit versions of Java. We now have a vendor telling us we need Java 6 32-bit for their software to work.

What happens if we add the 32-bit version? Does the 32-bit take over as the default JVM because it was installed second? Are there any pitfalls or problems we should be aware of related before we have 32-bit and 64-bit JVMs installed simultaneously?

I know you can control what JVM is being used. I have done it on IBM i but I am far more familiar with the process on Windows and Linux. Looking for advice, tips and best practices.

Thanks in advance.
