icedtea-web compatible with OpenJDK11

Sat Sep 8 19:20:08 UTC 2018

Thanks for sharing that, Laurent.  This is what I ended up testing on my Mac, with your archive installed in $HOME/Documents/icedteaweb-1.7-patched and http://jdk.java.net/11/ <http://jdk.java.net/11/> installed in $HOME/Documents.

That takes me about as far as I was previously getting with OpenJDK 11 on macOS; it launches my app, then fails in my application with security errors or native library issues that I don’t yet understand; I’ll keep poking at it.
