Description

Given a properties file like the one described in PropertiesConfigurationLayout:

demo.properties

 # A demo configuration file
 # for Demo App 1.42

 # Application name
 AppName=Demo App

 # Application vendor
 AppVendor=DemoSoft


 # GUI properties
 # Window Color
 windowColors=0xFFFFFF,0x000000

 # Include some setting
 include=settings.properties
 # Another vendor
 AppVendor=TestSoft

The documentation states

For the property AppName one comment line and one leading blanc line is stored.

But the format actually thinks there is no leading blank line for AppName :

final PropertiesConfiguration properties = new Configurations().properties(new File("demo.properties"));

final int blankLinesBefore = properties.getLayout().getBlancLinesBefore("AppName");
assert blankLinesBefore == 1 : "Blank lines before for first property not correct";
