Bob Marinier commented on CONFIGURATION-840:
--------------------------------------------
I meant to say, I really did try this with every non-beta version from 2.0 on,
and they all show the issue.
> StackOverflowError when adding property

> Key: CONFIGURATION-840
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-840
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 2.0, 2.1, 2.1.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8.0,
> 2.9.0, 2.10.0

> 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

> As this appears to involve delimiter handling I even tried to configure it to
> use the DisabledListDelimiterHandler (not part of the reproducer), but this
> had no effect.
