What version of Conscrypt are you using? That stack trace doesn't match the current finalizer code, which has a null check for ssl and which hasn't changed in the last couple of years.

Also, I'm not sure whether ConscryptFileDescriptorSocket will work reliably on openjdk 13, see issue #737, in particular the suggestion to use ConscryptEngineSocket instead (which will be the default soon).
