Change syntax to avoid javac 8 compilation errors

It seems like neither Eclipse ecj nor javac in Java 11 complains when
using constructor references in these very special cases used for unit
testing. But javac in Java 8 does. So, we're now using lambda
expressions in place of constructor references: this seems to make all
compilers happy.
