How come the FindJNI module doesn’t expose libjsig for linking? libjsig is needed if any other part of the program overrides the signal handlers for SIGSEGV and a couple others. See [https://docs.oracle.com/javase/8/docs/technotes/guides/vm/signal-chaining.html](https://docs.oracle.com/javase/8/docs/technotes/guides/vm/signal-chaining.html).

Thanks

Looks reasonable to me. Please file an issue to add a `jsig` component to one of the find modules for Java.
