tomcat with laptop + windows sleep

[Alex O'Ree]

I've noticed a behavioral difference from tomcat 7 to 8.5. In v7, I used to
be able to put a computer to "sleep" with tomcat running. On resume,
everything would be just fine. On tomcat 8.5, i'm noticing that all
database connections are basically dropped and do not appear to to
restart/resume when the computer resumes. Actually the whole computer runs
super slow until i kill the tomcat process. I'm not entirely sure what's
going on here. Has anyone else noticed this kind of behavior?
