action-default package in Struts 2

Is there a package like action-default associated with Struts2 ?

I am not sure which jar(struts-core or plugins) it comes from but it was residing in my struts.xml for years. We had used struts-core-2.1.8.

I updated the struts version to 2.3.8 and struts started complaining,

I couldn't find any references for action-default package. Could anybody please help me figure out what is available in action-default package and the alternatives in Struts 2.3.8.

EDIT:

I couldn't post the complete struts.xml, it's too long. The package declaration is as below,

<package name="default" extends="struts-default,jfreechart-default,json-default,action-default">

Artifact Id of Struts related jars used:

struts2-core 2.1.8

struts2-convention-plugin 2.1.8

struts2-spring-plugin 2.1.8

struts2gwtplugin 0.2.1

struts2-jfreechart-plugin 2.1.6

struts2-jquery-plugin 3.5.0

struts2-json-plugin 2.1.8.1

With all the above mentioned jars struts didn't complain about the "action-default" package.

After updating the following jars to version 2.3.8, struts starts complaining that the package is missing,

struts2-core 2.3.8

struts2-convention-plugin 2.3.8

struts2-spring-plugin 2.3.8

struts2-json-plugin 2.3.8

There's no such package name action-default in the Struts default configuration the package name is struts-default. Change the name of the package which your package extends.
