As a result of JDK-8253228, a VM crash occurs for incorrectly specified JVMCI options. For example:

> java -XX:+UnlockExperimentalVMOptions -XX:+EagerJVMCI -XX:+UseJVMCICompiler -Djvmci.InitTiimer=true
Uncaught exception exiting JVMCIEnv scope entered at src/hotspot/share/jvmci/jvmciRuntime.cpp:626
java.lang.IllegalArgumentException: Could not find option jvmci.InitTiimer
Did you mean one of the following?
    jvmci.InitTimer=<value>

This is too heavy weight. It should resemble how -XX parsing errors are reported:

> java -XX:-UseOnStackReplacemen -version
Unrecognized VM option 'UseOnStackReplacemen'
Did you mean '(+/-)UseOnStackReplacement'? Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
