exclusions tag in geronimo-connector\pom.xml

[Vamsavardhana Reddy]

I see the following xml fragment in modules\geronimo-connector\pom.xml

       <dependency>
           <groupId>org.tranql</groupId>
           <artifactId>tranql</artifactId>
           <scope>test</scope>
           <exclusions>
               <exclusion>
                   <groupId>commons-logging</groupId>
                   <artifactId>commons-logging</artifactId>
               </exclusion>
           </exclusions>
       </dependency>

Can someone tell me the use of this <exclusions> tag.  If I comment out the
exclusions part, I am able to build this module using IBMJDK1.5.0.
Otherwise it is giving compilation errors like the following.

C:\G1.2\modules\geronimo-connector\src\main\java\org\apache\geronimo\connector\o
utbound\ManagedConnectionFactoryWrapper.java:[33,34] package
org.apache.commons.
logging does not exist

Or are these compilation errors due to a problem in IBMJDK1.5.0?
