Threaddump view is not filled

[albfan]

I just compare a file opened in old jar

https://samuraism.jp/samurai/en/samurai.jar

and latest version here

https://github.com/yusuke/samurai/releases/download/2021.9/samurai-swing-2021.9.jar

with old I see the threaddump panel filled, but with new one Threaddump panel is empty
