Unfortunately, Java is being locked down even further, so the hoops you have to jump through to run Bendometer is quite prohibitive, and I don't expect folks to have to figure this out. I'm working toward a version that won't have this complication, but not sure when it will be ready, although I'll post when it is ready.
Obviously, I'll be extending everyone's accounts because of this. The easier way to run Bendometer would be to use an older version of Java.
For the non-feint of heart the solution at this point is outlined here in this answer from StackOverflow:
Again, I don't expect anyone to follow this solution, but here it is for those that might be interested.
-----------------------------
The problem is caused by Oracle disabling hash algorithms which are no longer considered to be secure. Take a look at
JRE_HOME/lib/security/java.security
It contains the following properties:
jdk.certpath.disabledAlgorithms
jdk.tls.disabledAlgorithms
You can adjust them appropriately. For example, remove MD5 from the former and MD5withRSA from the latter.
