Hello Pierre,

Thank you for such a wonderful application.

But whenever I try to run jvarkit, I get the following error:

As I understand, this has something to do with CloserUtil from samtools. So do I re-install samtools with lower version of Java ? (that would be a nightmare for other pipelines running in my server)...what would your suggestion ?
