Another question, if I may?

So if I do a "make hotspot" it replaces the compiled Hotspot binary in the exploded build image?

The reason I ask is that this is what I tried, and it didn’t appear to show up in the list of "PrintFlagsFinal" output.

    This is correct. Using the exploded image as described is the shortcut 
    we have. The actual images are always built using jmod/jlink and yes, 
    that requires quite a bit of extra build time.
    
    If you are in JDK 8, you need to run "make jdk" to get the exploded 
    image updated with the new libjvm.so.
