As this article says, a start level is simply a non-negative integer value. But I checked the start level of "org.eclipse.osgi" in \configuration\org.eclipse.equinox.simpleconfigurator\bundles.info

org.eclipse.osgi,3.18.100.v20220817-1601,plugins/org.eclipse.osgi_3.18.100.v20220817-1601.jar,-1,true

-1 ? Why ?

CodePudding user response：

This is the value of the BundleInfo.NO_LEVEL constant - which means this bundle doesn't have a start level.

org.eclipse.osgi contains the EclipseStarter class which contains the main entry point. It is called by Java rather than being started by the OSGi framework.
