Log system info and remove paperclip java 9 warn

Removes the paperclip Java 9+ warning and replaces it with general
JVM and Host OS information that will be more useful in finding issues
for end users and ourselves.

Also removes the "for development only" 1.13 warning that everyone has
been ignoring completely anyway.
