require 'grpc' doesn't work on latest dev version on macOS

[frvade]

Hi all, thanks for your great efforts on speeding up ruby!

We're trying to switch to truffleruby on our project with GRPC and now expecting problems installing it on macos

First, it seems that this issue affects all macs, not only M1. But the latest dev version actually let the grpc gem be installed.

Second, after installation requiring the grpc gem on mac OS causes an (java.lang.NullPointerException).

How to reproduce

irb(main):001:0> require 'grpc'

Stacktrace

<no message> (java.lang.NullPointerException)

@eregon mentioned that there is an internal issue for this (GR-40811).

Thank you for the report, we'll look into it.

FWIW here is the error on JDK19 with more details:

Cannot load from object array because "this.globalContainers[id]" is null (java.lang.NullPointerException)
        from com.oracle.truffle.llvm.runtime.LLVMLanguage$LLVMThreadLocalValue.getGlobalContainer(LLVMLanguage.java:321)
...

[eregon]

This is fixed now.
