Daniel H. Peger created CONFIGURATION-795:
---------------------------------------------
Summary: Blanc lines before always 0 for first property despite
header comment
Key: CONFIGURATION-795
URL: https://issues.apache.org/jira/browse/CONFIGURATION-795
Project: Commons Configuration
Issue Type: Bug
Components: Format
Affects Versions: 2.7
Reporter: Daniel H. Peger
Given a properties like the one described in
[PropertiesConfigurationLayout|https://commons.apache.org/proper/commons-configuration/apidocs/org/apache/commons/configuration2/PropertiesConfigurationLayout.html]:
{noformat}
# 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
{noformat}
The documentation states
bq. For the property {{AppName}} one comment line and one leading blanc line is
stored.
But the format actually thinks there is no leading blanc line for {{AppName}} :
{code}
final PropertiesConfiguration properties = new Configurations().properties(new
File("demo.properties"));
final int blancLinesBefore =
properties.getLayout().getBlancLinesBefore("AppName");
assert blancLinesBefore == 1 : "Blanc lines before for first property not
correct";
{code}
