I think this looks okay but I think @JimLaskey and/or @sundararajana should
look at this because it creates a dependency on a JVM_* function. I'm trying to
think if there are any interop issues when using jrtfs. Jim/Sundar can correct
me but I think we are okay there because a tool on say JDK 8 (or 11 or 17) that
accesses a JDK 19 run-time image will use the BasicImageReader and won't use
libjimage in the target VM.
