jrtfs should use the native implementation when targeting the current
runtime of course.
However, when the target runtime is different then the safest is to
use the pure-java implementation. I think this will become more
obvious when jrtfs is updated to work on JDK 9 but targeting a
different JDK 9 build.
I also think it's a better approach for jrtfs to use pure-java
implementation when targetting a different runtime. Perhaps you can add
a method SystemImages::isCurrentRuntime (something like that) that
BasicImageReader can use to determine if it should use
ImageNativeSubstrate or ImageJavaSubstrate.
