though II'm not sure which Karaf version is supposed to be able to start with java 11, it is somethign that we will have to modify

it is automatically adding:
-Djava.ext.dirs=C:\install\jdk\jdk-11.0.2\jre\lib\ext;C:\install\jdk\jdk-11.0.2\lib\ext;C:\install\fuse-runtime\7.2\fuse-karaf-7.2.0.fuse-720035-redhat-00001\lib\ext -Djava.endorsed.dirs=C:\install\jdk\jdk-11.0.2\jre\lib\endorsed;C:\install\jdk\jdk-11.0.2\lib\endorsed;C:\install\fuse-runtime\7.2\fuse-karaf-7.2.0.fuse-720035-redhat-00001\lib\endorsed

but java.ext.dirs and java.endorsed.dirs are alaways readded

by default there are also Unsyncclassload which is provided and which needs to be removed
