Description

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..?!
