Hi,
First note that:
$ jexec
can't locate java: No such file or directory
$ ls -l /etc/alternatives/jexec
lrwxrwxrwx 1 root root 44 28 déc. 19:45 /etc/alternatives/jexec ->
/usr/lib/jvm/java-17-openjdk-amd64/lib/jexec
$ /usr/lib/jvm/java-17-openjdk-amd64/lib/jexec
Error: -jar requires jar file specification
Syntaxe : java [options] <mainclass> [args...]
(pour exécuter une classe)
ou java [options] -jar <jarfile> [args...]

ou java [options] -m <module>[/<mainclass>] [args...]

(sorry for the french output)
Second here is a diff output:

The two source files have been retrieved using Debian Code Search.
