IIUC, signal chaining is a link time question for native executable using hotspot(launchers), the `java` launcher in regular JDK build is disabled by default unless user preload the libjsig.

So, for the future jmod to support static linking, it could include libjsig.a or leave it out and have user to explicit download and link their native application.

As for the `java` launcher in hermetic java, we need to decide whether we want to support signal chaining by default, and update the test accordingly.
