Update:
Downgrading Java version to 8u181 fixed the problem. So, it looks to me that only 8u191 is affected.
Jenkins is not able to connect to any outside resource that should work with SSL. It is not possible to obtain a list of plugins, connect to remote slaves using SSH, etc.
Here is what I can fish out when I try to update the list of plugins:
