             Summary: JupIOFactory and trimming of newline & carriage return characters
                 Key: CONFIGURATION-737
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-737
             Project: Commons Configuration
          Issue Type: Bug
          Components: Expression engine
    Affects Versions: 2.4
            Reporter: Chris


I want to configure the line separator that should be used in my output via config file.

E.g. using the property 

L1=\n

and JupIOFactory as following:
{quote}{{public static Configuration loadConfig(String fileName) throws ConfigurationException {}}
{{ Parameters params = new Parameters();}}

{{ PropertiesBuilderParameters properties = params.properties();}}

{{ properties.setFileName(fileName)}}
{{ .setThrowExceptionOnMissing(true)}}
{{ .setIOFactory(new PropertiesConfiguration.JupIOFactory())}}
{{ .setListDelimiterHandler(new DefaultListDelimiterHandler(','));}}

{{ FileBasedConfigurationBuilder<FileBasedConfiguration> builder =}}
{{ new FileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfiguration.class)}}
{{ .configure(properties}}
{{ );}}
{{ Configuration config = builder.getConfiguration();}}
{{ return config;}}
{{ }}}
{quote}
The value of the property gets trimmed. Java Properties (JDK 8) does not trim newline and carriage return characters.

 

The problem seems to arise in the method at the following code part (DefaultListDelimiterHandler - where the string gets trimmed):
{quote}{{protected Collection<String> splitString(final String s, final boolean trim)}}

...

{{// Add last token}}
{{ String t = token.toString();}}
{{ if (trim)}}
{{ {}}
{{ t = t.trim();}}
{{ }}}
{{ list.add(t);}}
{quote}
