That is java usage output but you are right, it wasn't updated. We'll 
get that fixed.

The hashes are computed from the packaged modules (JMODs or modular 
JARs). The "Unable to compute ..." here is because the hashes checked at 
link time but aren't saved in the runtime image. There is a big refresh
