Oracle did it again...
The Java 8 update 40, which is released, breaks the smart-client totally on OSX Yosemite
The smart-client does download, but after that, you can't get any cursor in a field
The smart-client does not appear in the dock
if you have focus on the smart-client, there is no menu of the smart-client.
The only thing you can do, is close the client.
It appears (from the few tests we did) that it appears on OSX Yosemite only...
Will do some more tests.. when we have more info, we will let you know...
