Hi hatemmaihoob,

Thank you for reporting us the error. We are working to solve it. The hosting that hosts the binary files containing the benchmark datamodels has changed its configuration and no longer allows downloading files via HTTP. We are working on a solution to access these files via HTTPS. We expect to release a patch this week.

We have upgraded CF4J to version 2.3.0. This version should let you use BenchmarkDataModels again.
