Hi All, We are facing an issue with DNS server caching on RHEL-based distros: after the update of resolv.conf java application cannot resolve the hosts any more.
Reproducer is very simple: 1. Clean /etc/resolv.conf or connect to vpn and use vpn-only nameserver. 2. Launch the minimal java app [1]. 3. Restore the /etc/resolv.conf or disconnect from vpn (/etc/resolv.conf should be updated with accessible nameserver at this moment). 4. Notice that name resolution continues to fail. I've prepared a small webrev that fixes the issue [2], but would like to hear some ideas/criticism first. If the patch looks ok to everyone, please create an issue for this, and I will submit it for approval/sponsorship.
