> When a properties file has a line with a single space in it, calling getCanonicalComment(<propertyKey>,
false) on the PropertiesConfigurationLayout will throw a StringIndexOutOfBoundsException.
Below is the stack trace:
> {code}
> java.lang.StringIndexOutOfBoundsException: String index out of range: 1
> 	at java.lang.String.charAt(String.java:686)
> 	at org.apache.commons.configuration.PropertiesConfigurationLayout.stripCommentChar(PropertiesConfigurationLayout.java:768)
> 	at org.apache.commons.configuration.PropertiesConfigurationLayout.trimComment(PropertiesConfigurationLayout.java:741)
> 	at org.apache.commons.configuration.PropertiesConfigurationLayout.constructCanonicalComment(PropertiesConfigurationLayout.java:900)
> 	at org.apache.commons.configuration.PropertiesConfigurationLayout.getCanonicalComment(PropertiesConfigurationLayout.java:212)
> {code}
