If you had Java JRE 1.7.x before the OS upgrade, then be aware that version prior 1.8.x are not compatible/supported with OSX 10.10. I would suggest removing the old version using the terminal and the following command :

Then, download/install the latest Java JRE version from Oracle Web site [link]

If you are still experiencing that issue after this process (like I had with one of my computer), then try downloading and installing Java JDK 1.8.x (Development Kit) [link] instead, it solved the issue for me.
