You're welcome.

That's surprising because depending on where your office is, it may
just be a matter of walking down an aisle and knocking on a colleague's
door to get access to the necessary test setup given the fact that
Oracle is officially shipping and supporting Linux for SPARC [1,2].

Well, I'm not so sure. openjdk-9 did build in the past (b88), so I
don't think the code is completely bit-rotten [3].

Even for minimal build fixes like these?

I actually expect the Linux SPARC port to be picked up by Oracle
themselves in the near future. I can't really imagine that Oracle
would not be willing to support on of their one major software
products on one of their major platforms.

Thanks,
Adrian
