We have a Java EE application where we use JSF with Omnifaces (v 2.6.3) and Primefaces (v 6.1), deployed on GlassFish v 4.1.2.
Although the application runs correctly (I can navigate the pages and use them) we have some warnings in the logs regarding some classes that cannot be found in both of omnifaces and primefaces. Yes, warnings about a "ClassNotFound exception", so it's not the exception in and of itself, just warning about it, after the warnings, the server continues to run normally and deploys my application successfully.
This happens both with Eclipse and with asadmin, manually.
The structure of the application is like this (I have one EJB app, one web service app and the JSF one that triggers the warnings):

omnifaces-2.6.3-javadoc.jar
omnifaces-2.6.3.jar
primefaces-6.1-sources.jar
primefaces-6.1.jar
If I move the primefaces library in the EAR's lib directory then the warnings related to primefaces are gone.
Altough this is not a proper solution, primefaces is "local" to the JSF app, and omnifaces as well (if I try to move the omnifaces library I get some initializatoin errors, the application breaks).
What is the cause of this behaviour? How can I get rid of the warnings? Could there be latent bugs?
The warnings (there are more, this is only a small part of them):

I forgot to mention that the above setup also triggers this on a re-deploy with asadmin:
[glassfish 4.1] [WARNING] [NCLS-DEPLOYMENT-00023] [javax.enterprise.system.tools.deployment.common] [tid: _ThreadID=47 _ThreadName=admin-listener(2)] [timeMillis: 1511441893194] [levelValue: 900] [[
Ignoring JSFapp_war/ because the containing archive C:\glassfish4\glassfish\domains\domain1\applications\EAR recorded it as a pre-existing stale file]]
The stale files are exactly the libs in the JSF's WAR. If I move primefaces in the EAR, then only omnifaces remains stale upon re-deploy. What's up with this?
