---------------------------------------------
Summary: PropertiesConfiguration: Escape sequence handling
different from Properties
Key: CONFIGURATION-716
URL: https://issues.apache.org/jira/browse/CONFIGURATION-716
Project: Commons Configuration
Issue Type: Bug
Affects Versions: 2.3
Reporter: Patrick Schmidt
The escape sequence handling in PropertiesConfiguration is different from
java.util.Properties.
The Javadoc (of java.util.Properties) basically states that if an escape
sequence (backslash + character) is not understood, the backslash is simply
removed. PropertiesConfiguration keeps the backslash. E.g. "\ " (backslash +
space) should result in just a space. This sequence is used by Properties to
escape the first leading space in a property value when writing to a
properties-file. PropertiesConfiguration does not understand this syntax. Also
(which is technically a different issue but pretty close to this one) does not
preserve leading spaces in property values when saving. One could use \u0020 to
encode the first leading space, but it would be nicer if it could just use the
simpler "\ ".
