On my Macintosh, I received a notice that there is an updated version of Java v8 update 73 build 02 (released on February 5).
I called the US Patent Electronic Business Center (EBC), and it appears that their systems are down. At this time, I would suggest holding off on updating Java.
[updated on February 12] I called the EBC and talked to Agent 40. She said that this update is not fully supported yet but appears to be working fine.
