Hi,

While I was inspecting why src:openjdk-21 didn't get autoremoved, I
found out that sisc has this in its Depends: openjdk-jre | java2-runtime

openjdk-jre doesn't exist in Debian and openjdk-21 is the last source
package in testing that has binaries that Provide java2-runtime.

openjdk-21 has an open RC bug and we want to keep the amount of
openjdk's in testing limited anyways, so I'm going to help autoremoval,
which means I'll have to remove src:sisc.

I'm sorry for the late notice.

Paul
