Curiosity question I am seeing the ConfigurationConverter behave
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"));
07
08 Properties propString =
ConfigurationConverter.getProperties(confString);
09 assertEquals("80", propString.getProperty("port"));
10
11 Properties propInt = ConfigurationConverter.getProperties(confInt);
12
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

It seems for some reason since I used an int, the ConfigurationConverter
wants to treat the property as a list. However since I actually put an
integer into the property it errors out since it can not convert a
integer to a list.
This behavior seems odd. Why does it do this?
