Javadoc
A filesystem location that has no real meaning and should not be regarded as providing any sort of useful
information. The "modules" directory is the default location from which JBoss Modules looks to find
modules. However, this behavior is in no way controlled by the value returned by this method, nor is it guaranteed that
modules will be loaded from only one directory, nor is it guaranteed that the "modules" directory will be one
of the directories used. Finally, the structure and contents of any directories from which JBoss Modules loads
resources is not something available from this class. Users wishing to interact with the modular classloading
system should use the APIs provided by JBoss Modules.
