C2: Object field load floats above its null check resulting in a segfault

ADDITIONAL SYSTEM INFORMATION :
Java 17 / ubuntu

This is a CI/CD env so I don't have full access to get exact version numbers for the OS.

A DESCRIPTION OF THE PROBLEM :
We've been building and testing Apache POI on different Java installs for years. On OpenJDK 17, the test runs regularly fail with a SIGSEGV failure.

REGRESSION : Last worked in version 16.0.2

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
* Check out https://github.com/apache/poi
* ./gradlew poi-ooxml:test
* warning - this can take quite a few mins to run

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Successful compile and test run
ACTUAL -
https://ci-builds.apache.org/job/POI/job/POI-DSL-1.17/38/ is one example build where this failed
