------------------------------------------
Summary: StackOverflowError when adding property
Key: CONFIGURATION-840
URL: https://issues.apache.org/jira/browse/CONFIGURATION-840
Project: Commons Configuration
Issue Type: Bug
Affects Versions: 2.10.0, 2.9.0, 2.8.0, 2.7, 2.6, 2.5, 2.4, 2.3, 2.2,
2.1.1, 2.1, 2.0
Reporter: Bob Marinier
Attachments: reproducer.zip
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.
