slightly ot: java9 runtime images

[Danno Ferrin]

I looked at the man pages, and it’s not there.  That is strange because I remember working with the docs people to get them the info they needed.

The best docs are from my JavaOne presentation:  
https://oracleus.activeevents.com/2014/connect/fileDownload/session/3B139AAF656DC1741328669FE873981E/CON2247_Ferrin-8u20%20packager.pdf <https://oracleus.activeevents.com/2014/connect/fileDownload/session/3B139AAF656DC1741328669FE873981E/CON2247_Ferrin-8u20%20packager.pdf>

As far as java callbacks… the support is fairly basic at the moment.  You own the JVM w/o a security sandbox so you can add standard shutdown hooks as well as other libraries that react to unix signals.  Signals are non-standard as the current Java signal classes exist in sun.misc.*, hence they an internal API and will not be accessible in JDK 9 (without contortions).

For windows a custom service executable is created.
For Linux init.d scripts are added.
For Mac launchd is used.
