[Bug] Cryostat failed to connect to JVM targets over IPv6 #964
Description
Current Behavior
When running cryostat and a sample app in an IPv6-enabled k8s cluster (i.e. pod only have IPv6 internal IP), some error occurred:
2025-07-01 18:31:10,700 WARN [io.cry.tar.TargetConnectionManager] (executor-thread-17) java.lang.IllegalArgumentException: invalid authority: fd01::8fe3:74d9:1635:18a7:2585.monitoring.pod:9097
2025-07-01 18:31:11,527 WARN [io.cry.cor.net.JFRConnectionToolkit] (executor-thread-11) connection attempt failed.
Getting pod IP (internal):
$ kubectl get pods quarkus-test-654659cbbb-z6csh -o=wide

Expected Behavior
Cryostat should be able to connect to the target and no errors occur.
Steps To Reproduce
- Have an IPv6 cluster ready. If using kind, you can use the following configurations:
kind: Cluster apiVersion: kind.x-k8s.io/v1alpha4 networking: ipFamily: ipv6 - Install cryostat via helm chart or the operator
- Deploy a sample JVM app
Environment
- Environment: k8s v1.32 with only IPv6 podCIDR and serviceCIDR
- Version: Cryostat 4 (latest snapshot or latest v4 release)Anything else?
