inline record ref projection contains an empty record attribute

[Srikanth]

Hi Remi,

Thanks for the problem report. 
https://bugs.openjdk.java.net/browse/JDK-8251041 tracks the issues 
relating to inline records.
We know of quite a few issues. (including reported by you in the past) - 
Jim is looking into these.
