The latest JVM SR16FP20 - 20160321_105735 will not install on top the previous JVM SR16FP20 20160129_110037.
I first installed the original JVM SR16FP20, only to find that it disables the Domino Console on the server.
I have now tried to install the latest 'fixed' JVM SR16FP20 - only to get the error message 'This patch is for JVM SR16FP15'.
According to the release notes - this patch is to fix the problem created by the original SR16FP20 ?!?
