Dear Logback team,

I am trying to optimize logback.xml file in our environment. Logging directory location we are specifying in more than one location so I am trying to create a variable ( property ) to hold log directory and reuse. Now problem is if path is “D:\seeta\log” then logback is stripping out all back ward slashes and giving it as “D:seetalog”. I know if I use forward slash or double slash it works fine but I cannot control the user who use my tool. Can you please help us in fixing it?

Working scenario
=============
<configuration>
…
<fileNamePattern> d:\seeta\log\cd_core.%d

{yyyy-MM-dd}.log</fileNamePattern>
…
</configuration>

NON-Working Scenario
==============
<configuration>
…
<property name="log.dir" value="d:\seeta\log"/>
…
<fileNamePattern>${log.dir}\cd_core.%d{yyyy-MM-dd}

.log</fileNamePattern>
…
</configuration>

NOTE : I have attached logback.jar and configuration files. Here logback_working.xml is existing configuration and trying to modify to {{ logback_NOT_working.xml}}

Regards,
Seeta Vadali
