[9] RFR 8146653: Debug version missing in hs_err files and on internal version after Verona

[Alejandro E Murillo]

Please review the following fix for JDK-8146653 
<https://bugs.openjdk.java.net/browse/JDK-8146653>:
Debug version missing in hs_err files and on internal version after Verona

Webrev: http://cr.openjdk.java.net/~amurillo/9/8146653/

Background:
Verona removed the debug info from version related system properties and 
that's now specified on a new system property called jdk.debug.
The version header spitted in hs_err files was updated to include debug 
info based on that change.
That info was also missing on the output for -Xinternalversion

Thanks
