RFR (L, final): 8218626: Add detailed message to NullPointerException describing what is null.

[Lindenmaier, Goetz]

Thanks, Coleen!

Finally jdk/submit completed.  I'll push now.

I would like to update the JEP text with the latest
changes to the message, also I would like to persist
the example file in JBS.
Do you think it is ok to still modify the JBS issue?

Once more many, many thanks for your help in 
driving the JEP forward, I would never have made 
it without you!

Best regards
  Goetz.
