Installation ./standalone.sh script hangs

Hi Ladies and Gents,

I was hoping to get help with the installation.
The thing is that I am experiencing an installation process using the so called ./standalone.sh script.
The issue is 100% reproducible in both RHL 7 and 8.
The installation script will just hang during the process when setting the web interface in exactly this phase:

19:28:51,564 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://127.0.0.1:9990/management

19:28:51,564 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://127.0.0.1:9990

From here the script just stops, no errors or confirmation that all successfully Completed or unsuccessfully failed.

Many thanks on advance.
