I am using TomEE 7 and JSF 2.2.
I use ajax in a commandButton and it worked fine. But suddenly (not sure what exactly has changed in the application), it is not working, and the commandButton refreshes the page. Checking the JS console it says:
Uncaught ReferenceError: mojarra is not defined
at HTMLInputElement.onclick
So thanks to this post I discovered that the JSF script was not accessible. So it was loaded in the page:
<head id="j_idt3">
....
<script type="text/javascript" src="/myApp/javax.faces.resource/jsf.js.xhtml?ln=javax.faces&stage=Development"></script>
</head>
But if I try to load the script directly in the browser I get a 500 error, and the logs in TomEE say this a bunch of times:

So I am now a bit lost on what to try or which direction to go for further research of the problem. Any ideas?
UPDATE
After some testing I have seen that one of my new added dependencies (I am using Maven) seems the responsible for the error. How a dependency can interfere the JSF libraries I don't know. Any suggestion on how I can continue isolating the problem?
