Bug#1012215: gradle-debian-helper: unknown option --add-opens breaks OpenJDK 11 packages

[Markus Koschany]

Package: gradle-debian-helper
Version: 2.2
Severity: serious
X-Debbugs-Cc: apo at debian.org

Hi,

The newly added --add-opens option is only valid for OpenJDK 17. I
understand that we switch to it for Debian 12 but it currently breaks
all packages that are built with OpenJDK 11. I am currently in the
process to update gradle to a newer upstream release. We should try to
use a conditional clause depending on the JVM in use.
