Cannot start Java 11 with JMX enabled in Ubuntu

When trying to start a Spring Boot app with a JRE locally installed in the host system (under `/run/host/usr/lib/jvm/java-11-openjdk-amd64`), I get the following exception on startup:

Error: Config file not found: /run/host/usr/lib/jvm/java-11-openjdk-amd64/conf/management/management.properties

That file actually exists, but it's a symlink that points to `/etc/java-11-openjdk/management/management.properties`, which is probably not "visible" to the flatpak (it should be mapped to /run/host/etc/java-11-openjdk/management/management.properties). If I disable JMX, it works instead, but this disables Spring Boot app Lifecycle Management.

Is there a workaround?

Reproduza a falha de inicialização com um aplicativo Spring Boot usando o Java 11 instalado no host e com JMX habilitado. Inspecione como o Flatpak expõe /run/host/usr/lib/jvm/java-11-openjdk-amd64/conf/management/management.properties e seu link simbólico /etc/java-11-openjdk/management/management.properties. Está concluído quando o arquivo é resolvido dentro do Flatpak e o aplicativo inicia com JMX habilitado.
