Non urgent question on https://bugs.openjdk.java.net/browse/JDK-4834738 (Adding which Object is null to an NPE)

[Martijn Verburg]

Hi all,

The topic of adding more useful information to an NPE came up on the Java
Champions list and after some digging we discovered some implementations
elsewhere (SAP VM for example) and some historical conversations / issues.

https://bugs.openjdk.java.net/browse/JDK-4834738
http://mail.openjdk.java.net/pipermail/hotspot-dev/2014-April/013535.html

The bug is listed as won't fix but didn't have any explanation added to it
as to why.  Is it just a case that the JIT and/or other mechanisms strips
away that sort of information at runtime?

Cheers,
Martijn
