According to the JbossAS7Userguide Wiki, the domain/log/ directory is used for logfiles of host- and process-controller. This makes great sense to me, however in domain.bat, it uses a different path with a new toplevel directory process-controller/. I think this is wrong, I would suggest the follwoing changes:

build/src/main/resources/bin/domain.bat
- -Dorg.jboss.boot.log.file="%JBOSS_HOME%\process-controller\log\boot.log" ^
+ -Dorg.jboss.boot.log.file="%JBOSS_HOME%\domain\log\process-controller\boot.log" ^
I sent a github pull request, but I am not sure it was correct. I can add a issue if you like. Problem seems to exist in 7.0.2-final as well.
This is BTW fixed in the current master:
