Yosemite JRE problems

I cannot open any .odb files since upgrading to Yosemite. The installed JRE is 1.70_67 is showing in Libre Office but seems not to work. Same problem on all my Macs. What should I do? I tried reinstalling both JRE and Office in various ways-nothing works.

Viewing Preferences → Advanced → Java options

with my LO Version: on my MacPro with

OS X Yosemite 10.10.3

shows that I have JRE 1.6.0_85 already installed.

Suggest you try this combination.
