Bug#981974: vtk9: FTBFS with OpenJDK 17 due to unsupported javac source/target level 6

[Emmanuel Bourg]

Source: vtk9
Severity: important
Tags: ftbfs sid bookworm
User: debian-java at lists.debian.org
Usertags: default-java17

vtk9 fails to build with OpenJDK 17 because it invokes javac with
the source/target options set to 6. Since OpenJDK 12 the minimum
version supported is 7.
