Thanks for your reply. Sorry just managed to reply today.
Btw, I'd follow your guide to update the grep in our Suse, but upgrading the grep seem not resolved this issue.
I've also try to install the latest Wildfly just now, it throwing the same error message.
Im thinking to install Bitnami Wildfly in Centos7 server then copy all to Suse, but not sure this is good idea or not.
Thank you in advanced.
