In 5.5. Debug Security Manager Policies in Procedure 5.3. Enable general debugging there are "bin/domain.conf.bat file for Windows", but in windows there is "\" instead of "/" (take a look at next line where is path bin\standalone.conf.bat for windows). Notation in path for windows should be same, I think that in bin/domain.conf.bat should be "\".
Moving to ON_QA. The changes should be available for review on the documentation stage within an hour or so from this comment. http://documentation-devel.engineering.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/
Verified on stage.
