----------------------------------------
Resolution: Invalid
This is the default list handling behavior of Commons Configuration. A
description (and a possible solution for your problem) can be found here:

> Advanced Java MessageFormat patterns not respected
> --------------------------------------------------

> Key: CONFIGURATION-449
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-449
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 1.6
> Reporter: Maxx
> Fix For: 1.7
>
>
> Hi,
> I'm using a standard Java properties file, containing this :
> my.label = Year {0,date,yyyy}
> The problem I encountered is that this pattern (*) is truncated while loading
> it with Apache Commons Configuration:
> (service code)
> // confPath being the path to an .xml file containing all the
> .properties file paths
> ConfigurationFactory configurationFactory = new
> ConfigurationFactory(confPath);
> configurationFactory.setBasePath(getApplicationRoot());
> configuration = configurationFactory.getConfiguration();
> (client code)
> String labelPattern = configuration.getString("my.label");
> I have labelPattern = Year {0
> which ended in the MessageFormat with a java.lang.IllegalArgumentException:
> Unmatched braces in the pattern.
> So I have to escape the commas in my pattern with a single backslash (here I
> had to enter two, because one backslash isn't displayed):
> my.label = Year {0\\,date\\,yyyy}
> Don't understand why..?!
> (*) see
