> In the attached reproducer, I attempt to add a Path object to a configuration
> programmatically. This results in a StackOverflowError.
> To reproduce, run with:
> {code:java}
> mvn test{code}
> It may be that adding a Path object is not supported (indeed, when I did this
> I meant to add it as a String), but even so it should not result in a
> StackOverflowError.
> The start of the stack is shown below (this just the last two lines just
> repeat until overflow):
> {code:java}
> java.lang.StackOverflowError

> use the DisabledListDelimiterHandler (not part of the reproducer), but this
> had no effect.
