----------------------------------------
Hi
same problem with OpenJdk 22
openjdk version "22" 2024-03-19
OpenJDK Runtime Environment (build 22+36-2370)
OpenJDK 64-Bit Server VM (build 22+36-2370, mixed mode, sharing)

My workaround is to set system property
org.apache.cxf.transport.http.forceURLConnection=true
