JDK-8275868 - ciReplay: Inlining fails with "unloaded signature classes" due to wrong protection domains
Description
The fix for JDK-8275868 only works if the class file for the method to be replay compiled is present. Otherwise, it results in a SIGSEGV because it tries to access the protection domain of a failed to load class (i.e. a NULL pointer).

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007ffff66063c6, pid=236864, tid=236868
#
# JRE version: Java(TM) SE Runtime Environment (18.0) (slowdebug build 18-internal+0-2021-11-01-1028080.christian...)

Comments
Fix request [17u] I backport this as follow-up of JDK-8275868. Small adaptions needed. Test passes and fails without the fix. SAP nightly testing passed.
