Bug#1011185: multiverse-core: FTBFS with OpenJDK 17 due to unsupported javac source/target level 6

[Emmanuel Bourg]

Source: multiverse-core
Version: 0.7.0-5
Severity: important

multiverse-core 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.
