Gluon Client Plugin Android app size realy big

Question

I'm using the new Gluon Client Plugin to develop android/ios apps with graalvm & javafx. It works quit well, but why by comparison to the gluon mobile 5.0.X the installed app is so big?

Thats my pom. Maybe its something wrong with the <reflectionlist/>? If I remove all the relfectionList-entries the apps crashs.
