Actually it's that that I feared that I would lose Java 6 support.  I was HOPING that I would lose Java 6 support and would gain Java 7.  I would really like it to work on a machine which did not even have jdk6 loaded on it.

IBM i 7.3 will require Domino 9.0.1FP6 or higher to run.
Since IBM i 7.3 will not support Java 6 this goes to say that Domino 9.0.1FP6 will not require Java 6.

For confirmation you can check out:
IBM i 7.3 Software Upgrade Planning

<snip>
Upgrade to 5733-LD9 IBM Domino 9.0.1 Fix Pack 6, when available.  Refer to the Collaboration and Social(Lotus) Software for IBM i Compatibility Guide for other Collaboration and Social software supported on IBM i 7.3.

Check out the compatibility guide.

As soon as I can download 9.0.1FP6 I will do so and get it running on one of my IBM i 7.2 lpars.
Then I will remove JDK6 and start them back up and see if they continue to run.
FP5 will not support the http task or the console command "show jvm" if JDK 6 is not loaded on your system, irregardless of how you have the JAVA_HOME setting.
If FP6 truly fixes that, then I will upgrade them to IBM i 7.3.
