I opened a command line and launched java manually and it worked and was 1.8 dot something which is should be OK.
I recently upgraded OnCommand to 3.1.2 RC1 which fixed my last set of connection (500 errors) issues. Of course I had to make some command line changes to the NetApp box which is a pain in the ass since I never remember the console password. However, it was working OK.
Maybe Java upgraded, I can't remember but OnCommand stopped working. So, I installed 3.1.2 RC2 which the links in this forum post said I needed to do http://community.netapp.com/... But, it still would not launch.
So, I poked around on my system look for rogue Java executables. Sure enough I found some in "c:\windows\system32". Since this is in the path earlier that the real java path, every time I launch System Manager, this java was invoked. System Manager could be better written to show an error but it isn't, so we just see nothing.
I deleted the java files in the c:\windows\system32 folder and System Manager launched perfectly.
