and there is new crash in

The issue is easy reproduced when just running "java -version" with AOTed java.base and with -XX:+EnableJVMCI.

Steps to reproduce:

> make run-test TEST="java/lang/Integer" TEST_OPTS_AOT_MODULES="java.base" TEST_VM_OPTS="-server -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseAOTStrictLoading
