Question about a Candidate Jep.

[A Z]

-I have been directed to this OpenJDK email list in order to inquire
about a particular candidate JEP.

https://bugs.openjdk.java.net/browse/JDK-8175916

-What is going on about implementation of JEP 306?  If not
for the change in defaulting that it suggests, what is happening
in terms of an alternate floating point mode?
