How to specify backslash '\' (e.g. Windows path) as a value in JBoss CLI

Issue

• How do I set backslash '\' (e.g. Windows path) as a value in JBoss CLI?

• I tried the following CLI:

  /system-property=example.lib.dir:add(value="D:\example\lib") 
  

  or

  /system-property=example.lib.dir:add(value="D:\\example\\lib") 
  

  but backslash '\' disappeared and the system property example.lib.dir was set as "D:examplelib".
