JDK-8217230 is a regression by JDK-8214862 (https://bugs.openjdk.java.net/browse/JDK-8214862).
JDK-8214862 was backported to openjdk8u272, but JDK-8217230 is not there.
This bug was triggered only once for this test case in my local jtreg run (hard to reproduce):
Patch does not apply to 8u cleanly due to changes in surrounding context in file compile.hpp.
The fix is simple and should be low risk (it removes a dead node from the C2 IR).
Performed full jtreg test with fastdebug build on x86_64 Linux.
OK to backport?
