Precedence of modules with identical names?

[lafr]

Due to 3rd party app additional modules to the modules folder.

Example:

<module xmlns="urn:jboss:module:1.3" name="com.fasterxml.jackson.core.jackson-annotations">

provided by Wildfly 9 by default in

$JBOSS_HOME/modules/system/layers/base/com/fasterxml/jackson/core/jackson-annotations/main/

and the identical module, perhaps with different version, in

$JBOSS_HOME/modules/com/fasterxml/jackson/core/jackson-annotations/main/ provided by 3rd party app.

Which one is used when referencing this module by name? Is this defined?

com/fasterxml/jackson/core/jackson-annotations/main/ first?

one directly in modules/ will be loaded first.

see Layered Distributions and Module Path Organization for details, segment "Translation of Filesystem Layout into Module Loading Precedence" talks about this.
