Subject [jira] Created: (CONFIGURATION-432) ConfugrationConverter treats properties different by type

ConfugrationConverter treats properties different by type

                 Key: CONFIGURATION-432
             Project: Commons Configuration
          Issue Type: Bug
          Components: Type conversion
    Affects Versions: 1.6
         Environment: Linux Ubuntu
            Reporter: Mike Power

The ConfigurationConverter is behaving differently depending on if I added an int or a string
to a configuration object.

Consider the following code:

01       Configuration confInt = new BaseConfiguration();
02       Configuration confString = new BaseConfiguration();
03       confInt.setProperty("port", 80);
04       confString.setProperty("port", "80");
05       assertEquals(80, confInt.getInt("port"));
06       assertEquals(80, confString.getInt("port"));
08       Properties propString = ConfigurationConverter.getProperties(confString);
09       assertEquals("80", propString.getProperty("port"));
11       Properties propInt = ConfigurationConverter.getProperties(confInt);
13       assertEquals("80", propInt.getProperty("port"));

As you can see the code is basically duplicated one set uses an int the other set uses a String.
 However an exception blows out of line 11.

'port' doesn't map to a List object: 80, a java.lang.Integer
org.apache.commons.configuration.ConversionException: 'port' doesn't map to a List object:
80, a java.lang.Integer
        at org.apache.commons.configuration.AbstractConfiguration.getList(
        at org.apache.commons.configuration.AbstractConfiguration.getList(
        at org.apache.commons.configuration.ConfigurationConverter.getProperties(

I interpreted the interface to mean that everything up to and include line 13 would pass.
