Exception on macOS with Java 16

[robert]

I am using Jide Common Layer in an application on macOS, using Java 16. Jide works with previous Java versions, but fails with Java 16 on macOS. I receive following exception:

Code: Select all

[JIDE Support]

You need to use --add-export jvm parameter to expose those classes to JIDE.

Thanks, that worked. In case anyone else encounters this issue, this is the jvm argument required:

Code: Select all

--add-exports java.desktop/com.apple.laf=ALL-UNNAMED
