More JVM Confusion !

I have been checking the JVMs (sh jvm) that did report successful updates and I am getting different results from the 2 Servers with 9.0.1FP3 installed.

These servers were built on the same day from the same installation files and are both at the same level of Domino, but report different results for their JVM releases ???

Server 1

Both these Servers reported successful installation of the latest JVM Patch (6 March 2015 on Fix Central) and have jvmpatcher logs which report success and a list of file names.

Can anyone advise what is going on ?
