When running on a system with the latest `java-runtime` (version 18-2 at time of writing), the application does not launch successfully due to removal of support for the `--ilegal-access=permit` option in Java 17.0 (see errors below). I believe the issue has been present since `extra/jre-openjdk` and related packages were bumped up to provide Java 18 on 2022-04-05.

This is a known problem, and there is a check to fallback to an earlier version of Java in such a case inside the `/usr/bin/sweethome3d` wrapper script. However, this check only filters out `java-17-openjdk` as a possible fallback option, not later releases such as the current `java-18-openjdk`. The aforementioned workaround is found around lines 30-44 in `/usr/bin/sweethome3d`, specifically on line 33:

$ bat -p /usr/bin/sweethome3d -r 30:44 -n
30 if [ $(vercmp "${JAVA_VERSION}" "17") -gt 0 ]
31 then
32 echo "Warning: Sweethome 3D actually is not compatible with Java version > 16"
33 _PREVIOUS_JAVA_VERSION="$(archlinux-java status | tail -n +2 | sort | cut -d ' ' -f 3 | sort -nr -k 2 -t '-' | grep -vE '17-' -m 1)"
34 if [ -z "${_PREVIOUS_JAVA_VERSION}" ]
35 then
36 echo "No others Java version are available, please install a Java version < 17"
37 exit 1
38 else
39 echo "Falling back to ${_PREVIOUS_JAVA_VERSION}"
40 export JAVA_HOME="/usr/lib/jvm/${_PREVIOUS_JAVA_VERSION}"
41 export JAVA_EXEC="${JAVA_HOME}/bin/java"
42 export JAVA_VERSION="$(${JAVA_EXEC} -version 2>&1 | head -1 | cut -d' ' -f 3 | tr -d '"')"
43 fi
44 fi

Recommend updating line 33 to also filter out Java 18 in the final `grep` expression to fix.

END-USER WORKAROUND: Manually force sweethome3d to call an earlier version of Java by setting the `JAVA_HOME` environment variable at runtime, e.g.
$ JAVA_HOME=/usr/lib/jvm/java-11-openjdk sweethome3d

Steps to reproduce:
1. Update system with `$ pacman -Syu` or otherwise install `jre-openjdk>=18` (at time of writing, `jre-openjdk` provides `java-runtime=18-2`).
2. Install at least one older version of the Java Runtime Environment is installed on the system, e.g. version 11 with `$ pacman -S jre11-openjdk`.
3. Ensure `java-18-openjdk` is set as the default Java (if needed):
# archlinux-java set java-18-openjdk
4. Attempt to launch Sweet Home 3D application. For me, a splash screen now pops up, but the application otherwise appears to hang here until forcibly killed. Errors when launched in a terminal are found below:
$ sweethome3d
Warning: Sweethome 3D actually is not compatible with Java version > 16
Falling back to java-18-openjdk
OpenJDK 64-Bit Server VM warning: Ignoring option --illegal-access=permit; support was removed in 17.0

it is actually enough to change the
grep -vE '17-' -m 1
grep -vE '1[78]-' -m 1

I have fixed to ignore java-18 and any newer version.

Also, I changed PKGBUILD to install latest version, 7.0.

I thought I could send pull request on github, but it's a read-only repository, but changes are in my fork:
