LibreOffice stopped opening password protected documents after upgrading to Java 8

Libre Office will no longer open Calc documents that are password protected. I upgraded to Java 8 a few days ago. Is that the reason?

I had LibreOffice 4.0 but I upgraded to 5.0 to see if it will help. Same result. I get a blank window with nothing inside it when I type in my password.

I downloaded the latest OpenOffice.org version and it opened the password protected files without incident. What gives?
