I actually somehow missed "8131326: Enable CheckIntrinsics in all
types of builds" which enabled CheckIntrinsics in product builds by
default (before it was only enabled in debug builds). Not sure what
was the rational behind this change (CC'ed Zoltan who did the change)
but I'm pretty sure that the effects of SetNativeMethodPrefix haven't
been taken into account when that change was made. In the end it paid
off, otherwise you wouldn't have found this issue :)
I mentioned the following in the RFR for 8131326:
"Problem: The CheckIntrinsics flag added by JDK-8076112 is currently
enabled only in debug builds. As a result, users of product builds might
easier oversee potential mismatches between VM-level and classfile-level
intrinsics."

I don't recall any other reason for doing this change, although somebody
might have asked me in a private message to do it (maybe with
more/different justification).
Best regards,
Zoltan
