Created attachment 821781 [details]
Example project

Description of problem:

When adding a THREADED_FILE or FILE Logger to a Rule Service I get a "ava.lang.ClassNotFoundException: org.xmlpull.v1.XmlPullParserException" during processing

Version-Release number of selected component (if applicable):

How reproducible:

Always

Steps to Reproduce:
1. In the attached project change the log path by going to the Rules Compent -> Properties -> Advanced -> Loggers and modify the value in the log column
2. mkdir inbox
3. Deploy the attached project
3. cp src/test/resources/test.csv inbox/


Actual results:

An error is shown in the console:

Expected results:

Rule is executed without errors and result is logged

Additional info:

I have fixed this by adding a module and changing the xstream one:

modules/system/layers/soa/com/thoughtworks/xstream/main/module.xml

<module xmlns="urn:jboss:module:1.0" name="com.thoughtworks.xstream">
    <resources>
        <resource-root path="xstream-1.4.3.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
    </dependencies>
</module>

Downloaded http://mvnrepository.com/artifact/xmlpull/xmlpull/1.1.3.1/xmlpull-1.1.3.1.jar into modules/system/layers/soa/org/xmlpull/main

Created modules/system/layers/soa/org/xmlpull/main/module.xml

<module xmlns="urn:jboss:module:1.0" name="org.xmlpull">
    <resources>
        <resource-root path="xmlpull-1.1.3.1.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
    </dependencies>
</module>

Changed modules/system/layers/soa/com/thoughtworks/xstream/main/module.xml

<module xmlns="urn:jboss:module:1.0" name="com.thoughtworks.xstream">
    <resources>
        <resource-root path="xstream-1.4.3.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
 	<module name="org.xmlpull"/>
    </dependencies>
</module>

Afterwards the error disappeared and information appeared in the log.

There is a similar issue reported here: https://bugzilla.redhat.com/show_bug.cgi?id=991526. This one may propose a different fix for EAP 6.2
