At this point, it just hangs.

Hello @petere, which Java version are you on? Based on some web searches, this is a Java 11 vs 17 issue. It is unclear to me which one is working: our CI uses Java 17 but the web sites I found point to Java 17 being the culprit behind this error. Which version are you on? (I use SDKman to quickly change between Java versions: https://sdkman.io/)

I was using

openjdk version "17.0.7" 2023-04-18
OpenJDK Runtime Environment Homebrew (build 17.0.7+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.7+0, mixed mode, sharing)

If I use

openjdk version "11.0.19" 2023-04-18
OpenJDK Runtime Environment Homebrew (build 11.0.19+0)
OpenJDK 64-Bit Server VM Homebrew (build 11.0.19+0, mixed mode)

then it works.

Hi! The project readme is unclear about this at the moment. tags/1.0.0 uses Java 11 and the upcoming 2.0.0 will use Java 17. I will update the readmes shortly.

Fixed by #386 and #389.
