TUSCANY-2506: Multiple versions of activation jars are pulled in by transitive dependencies

[Raymond Feng <en...@gmail.com>]

Hi,

When I debugged TUSCANY-2506, I found out that more than one versions of 
activation jars are pulled in by various 3rd party jars. For example:

[INFO] |  +- org.apache.abdera:abdera-core:jar:0.3.0-incubating:compile
[INFO] |  |  +- org.apache.abdera:abdera-i18n:jar:0.3.0-incubating:compile
[INFO] |  |  \- 
org.apache.geronimo.specs:geronimo-activation_1.0.2_spec:jar:1.1:compile


[INFO] |  \- org.apache.abdera:abdera-parser:jar:0.3.0-incubating:compile
[INFO] |     +- org.apache.ws.commons.axiom:axiom-api:jar:1.2.5:compile
[INFO] |     |  \- javax.mail:mail:jar:1.4:compile
[INFO] |     |     \- javax.activation:activation:jar:1.1:compile

[INFO] |  +- org.apache.axis2:axis2-codegen:jar:1.3:compile
[INFO] |  |  \- org.apache.axis2:axis2-adb:jar:1.3:compile
[INFO] |  |     \- 
org.apache.geronimo.specs:geronimo-activation_1.1_spec:jar:1.0-M1:compile

We only have one version is packaged in the binary distribution, but the 
generated ANT build.xml contains different versions such as:

    <fileset id="3rdparty.jars" dir="../../lib">
        ...
        <include name="activation-1.1.jar"/>
        ...
        <include name="geronimo-activation_1.0.2_spec-1.1.jar"/>
    </fileset>

Please note both activation-1.1.jar and 
geronimo-activation_1.0.2_spec-1.1.jar are not in the distro. As a result, 
the webapp is broken due to the classpath issue.

Any idea how we can fix it?

Thanks,
Raymond
