Java DNS lookups fail

User_5OLQ9Mar 7 2022

Hello
I have developed software for 25 years and have build search engines earlier to National Library of Finland etc.
I'm using a web crawler that has been in use more than 10 years but the Java software don't do DNS lookups anymore. I tried many different Java SDK versions but they all had the same problem. Packet capture showed that DNS packets are not even send by Java runtime but other Linux programs are ok and send proper DNS/UDP packets to LAN router.
Know you what has happened to Java?
Java is critical to our business and we plan to buy Java product from Oracle.
We really need help!!
