Bug#1030150: freeplane fails to start with java 18 (openJDK 18) and openJDK 17.

[Felix Natter]

Dear users,

you can download and install the .deb version that upstream provides:
- https://sourceforge.net/projects/freeplane/
- select "Files"
- select "freeplane stable"
- select freeplane_1.11.11~upstream-1_all.deb
- install with "sudo apt install /path/to/freeplane_1.11.11~upstream-1_all.deb"

(the file name of the stable version may change over time!)

Note this bug related to ibus:
https://github.com/freeplane/freeplane/issues/1069

You can also, as the reporter noted, switch to an old JRE (mind security
issues though!), either through JAVA_CMD or FREEPLANE_JAVA_HOME.

I cannot package freeplane-1.11.x for Debian because it requires
gradle >= 7.x.

I am discussing with the debian-java team whether to remove freeplane
from Debian/Ubuntu for security reasons (old JRE versions...), unless
you disagree strongly [1]!

Cheers and Best Regards,
