We do not need to publish a new installer to modify launcher arguments but should look at the P2.inf mechanism.
P2 offers a way for bundles to execute some commands at different stage of an installation or an uninstallation.
Commands can for example, change file rights, change JVM path, add/remove JVM launcher args, copy/delete files, etc.

New proposal¶
Add a p2.inf file to the root of org.txm.libs.javafx.feature containing the following touchpoint actions:
instructions.configure = org.eclipse.equinox.p2.touchpoint.eclipse.addJvmArg(jvmArg:-Dorg.osgi.framework.bundle.parent=ext); instructions.unconfigure = org.eclipse.equinox.p2.touchpoint.eclipse.removeJVMArg(jvmArg:-Dorg.osgi.framework.bundle.parent=ext);
