Hi Kim,

for XLC 16. Any information about "some C++14 features"? I haven't found any detail on that. we will user our internal connections to IBM to find out :)

Best regards, Goetz.

I haven't found any detail on that. I am working toward being able to target this for JDK 12, but realize that might not be reachable. Windows is already there, because of VS2017 support. There are a couple of minor patches needed for gcc and clang based builds; Linux-x64 and MacOSX-x64 have had a fair amount of ad hoc testing. We (Oracle) only switched over the Solaris/sparc builds to the necessary compiler version (Oracle Studio 12.6) very recently, and there are some issues still to be dealt with there. And the currently used XLC is just not up to the change.
