Hi All,

I have a route that start with a mina2 UDP endpoint:
<from uri="mina2:udp://0.0.0.0:8888" />

I installed the camel-mina2 feature and I deployed it to Servicemix (I'm
using 4.5.3),
but when starting the bundle with the mina2 route I got a NoSuchMethod
exception (see at the end).

The problem was that the camel-mina2 features uses bundle
  mvn:org.apache.mina/mina-core/2.0.7

but on Servicemix 4.5.3 the version 2.0.5 get installed due to feature
<feature name="ssh" description="Provide a SSHd server on Karaf"
version="2.2.11">
....
        <bundle start-level="30"
dependency='true'>mvn:org.apache.mina/mina-core/2.0.5</bundle>
....
</feature>

(from
apache-servicemix-4.5.3/system/org/apache/karaf/assemblies/features/standard/2.2.11/standard-2.2.11-features.xml)


I got it working by:
1. installing mvn:org.apache.mina/mina-core/2.0.7
2. stopping mvn:org.apache.mina/mina-core/2.0.5
3. updating mvn:org.apache.camel/camel-mina2/2.10.7 so to get it using last
version
4. restarting my bundle with the mina2 route


In the next version of camel or servicemix,
is it possible to have the feature camel-mina2 to require explicitly mina
>= 2.0.7 so that it is not required installing it manually?
or should be karaf ssh's feature to upgrade to mina 2.0.7?

(sorry I'm in a hurry now and can't open a JIRA ticket, also I don't know
if put it in camel, servicemix or karaf)

thank you.
Cristiano


PS: Here the exception's stack trace I got when camel-mina2 got resolved to
mina 2.0.5
