[8u] Request for enhancement backport approval for CR JDK-8171194: Exception "Duplicate field name&signature in class file" should report the name and signature of the field

[Shafi Ahmad]

Hi,

This changes required to improve the ability to diagnose issues in large projects. 
The information is available it is just that it is not being emitted in the exception message. 
This should fall under improvements to serviceability.

So may I get the approval of enhancement backport of 'JDK-8171194 to jdk8u-dev.

The enhancement backport request id is https://bugs.openjdk.java.net/browse/JDK-8176800

Regards,
Shafi
