Following up on this. As well as multi-branch pipelines the same issue 
occurs doing SCM checkouts in jenkins so I'm guessing it impacts quite a 
lot of java file access in jenkins and possibly in other things as well.

I took the patch from FreeBSD (attached) and added it as a local patch 
and the exception disappeared and my pipeline started working. I've been 
running with it for a while and jenkins (now 2.219) seems to be working 
stably with the patched openjdk8.

Looking at the FreeBSD SVN repo again they have upgraded to openjdk 
8u242 in where the patch is no longer required (presumably because the 
FreeBSD team got it into the upstream build).

I got the patch from:
https://svnweb.freebsd.org/ports/head/java/openjdk8/files/patch-jdk-make-mapfiles-libnio-mapfile-bsd?view=markup&pathrev=514690
