There is a typo: Main class : jlink.example.JLinkFeatures.class
Instead, it must be: Main-Class: jlink.example.JLinkFeatures.class

Re: can't open jar file
Does the class JLinkFeatures belong to a package? I guess you didn't specify a fully qualify name, such as com.mypackage.JLinkFeature, so that Java couldn't find the class.
