Bug#1052538: truffle: FTBFS with OpenJDK 21 due to unsupported javac source/target level 7

[Emmanuel Bourg]

Source: truffle
Version: 0.6-3
Severity: important
Tags: ftbfs sid trixie
User: debian-java at lists.debian.org
Usertags: default-java21


truffle fails to build with OpenJDK 21 because it invokes javac with
the source/target options set to 7. Since OpenJDK 20 the minimum version
supported is 8.
