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

[Jonas Andradas]

Package: freeplane
Version: 1.7.10-1
Severity: important
X-Debbugs-Cc: j.andradas at gmail.com

Dear Maintainer,

freeplane fails to start if invoked with Java 18 (OpenJDK 18), due to the
Security Manager being deprecated, apparently.

It still loads fine with OpenJDK 17, but the launch script just seems to use
the default Java in the system (/etc/alternatives/java), which can lead to
issues, as it would not start with later versions of OpenJDK.

It would probably make sense to restrict the Java version used, so if a
previous, working version is available, use that, until freeplane is able to
work under newer Java versions.

The observed error can be found below:
