In my case of writing a test case to deploy Resource Adapter as module, it needs to create a file META-INF/ra.xml into the test module.

I am using TestModule to set up the test module, and as a developer, I need to know where the server modules directory is, so that I can create the file and its directories to set it up. Now the method of 

static File getModulesDirectory(boolean create)

has package level modifier, I would like to have this method to be public so that it can be used in the test suite to add more content than normal jar resources.
