if kstat_open() fails here:

414     // Otherwise use kstat to determine the machine type.
415     kstat_ctl_t* kc = kstat_open();

..we may then use an uninitialized char* in the later assert:

434   assert(impl_m != 0, "Unknown CPU implementation %s", impl);

Yes, thanks for taking care of this Kevin.

Okay, thank you!

Martin noticed this when I was backporting a previous change, I said we'll take care of it.

The assert was added by JDK-8165482. [~mwalsh], could you please have a look?

ILW = Reading uninitialized char*, only with debug build on Solaris SPARC, no workaround = MLH = P4

Good catch.
