Re: [ jEdit-users ] Possible to install jEdit on a new Mac?

[Vampire <Va...@je...>]

Yeah, the issue with the naming scheme is reported at
https://github.com/TheInfiniteKind/appbundler/issues/55.
But when no matching version is found and as no `-F` is used, it should
then return a default and that should hopefully be 21 for you.
If that is the Java 8 one for you, it will then fail for the major version
comparison.
But if it returns the Java 21 one, it should usually work.

What are these four commands returning?

/usr/libexec/java_home -v 1.11+

jEdit.app/Contents/MacOS/jedit --verbose

echo $JAVA_ARCH

find $(/usr/libexec/java_home -V 2>&1 | grep Contents/Home | rev | cut -d '
' -f 1 | rev | sort -u) -type f -name libjli.dylib


Cheers
Björn
