Description of problem:
The RtFilter load vHostMappingFile but it's content is not processed and used.


Version-Release number of selected component (if applicable):
RHQ 4.12

How reproducible:
Always

Steps to Reproduce:
1. Install and configure RtFilter in JBoss EAP 6 standalone server as per [1].

2. Then Add following in web application web.xml :

<filter>
    <filter-name>RhqRtFilter</filter-name>
    <filter-class>org.rhq.helpers.rtfilter.filter.RtFilter</filter-class>
    <init-param>
        <param-name>vHostMappingFile</param-name>
        <param-value>vhost-mappings.properties</param-value>
    </init-param> 
</filter>

3. Create vhost-mappings.properties file (in jboss.server.config.dir) with below configuration :

jon.localhost.com = testvirtualserver
test1.example.com = testvirtualserver

4. Restart the JBoss EAP 6 server to reload the new changes.


Actual results:

The RtFilter loads vHostMappingFile but it does not read content of the vhost-mappings.properties file and call time metrics will be logged in the predefined file name.


Expected results:

The RtFilter loads vHostMappingFile, reads it and processes it so that call time metrics are captured in the correct files as defined in the vhost-mappings.properties file [2].
