Note JavaFX not being found should only prevent your use of the BrowserView addon, otherwise things should work fine.

The java 8 freeze issue you mentioned already has a ticket: https://github.com/zaproxy/zaproxy/issues/5585 and a PR has been opened with a fix. There's also a work around here: https://github.com/zaproxy/zaproxy/issues/5526#issuecomment-522015202

Solution:

1. Install openjfx apt-get install openjfx
2. Backup zap start script cp /usr/share/zaproxy/zap.sh /usr/share/zaproxy/zap.sh.20190925
3. Edit zap start script:
   a. vi /usr/share/zaproxy/zap.sh
   b. Change line 130, from: exec java ${JMEM} ${JAVAGC} ${JAVADEBUG} -jar "${BASEDIR}/zap-2.8.1.jar" "${ARGS[@]}" to: exec java --module-path /usr/share/openjfx/lib --add-modules=javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web ${JMEM} ${JAVAGC} ${JAVADEBUG} -jar "${BASEDIR}/zap-2.8.1.jar" "${ARGS[@]}"
4. Start zap via /usr/share/zaproxy/zap.sh

The BrowserView addon should now work fine, and you will no longer get warning on startup.
