debian testing, confusing message during upgrade openjdk-17-jre-headless

[songbird]

  during this morning's update run:

Setting up openjdk-17-jre-headless:amd64 (17.0.14+7-1) ...
update-binfmts: warning: current package is openjdk-21, but binary format 
already installed by openjdk-9


  ?  what does this mean to you?
