soffice --writer fails with 'com::sun::star::container::NoSuchElementException'

[mcmurchy1917techy]

I've had a successful compile of LibreOffice after cloning from 
https://gerrit.libreoffice.org/core

When running soffice It bombs out

> $ /home/alex/master/instdir/program/soffice --writer
> terminate called after throwing an instance of 
> 'com::sun::star::container::NoSuchElementException'

It doesn't give me much of a clue as to where to look.

Anyone give me a pointer as to where to start.

If it's any help I'm compiling against JDK11.
