[Axis2] Crash during Hot Update

[pi...@almerys.com]

Hi,
I encounter an issue with the hot update functionnality.
I deploy my Axis2 based web application, all the web services are 
deployed. Using Axis2 admin, I upload the same .aar file as the one 
included in the web app and I encounter this error:
[Timer-8] 2008-06-09 15:25:01,583 INFO  ServiceDeployer.java [deploy] The 
DEVPEC.aar service, which is not valid, caused

The WS uses JAXB2 databinding and crashes on this line:

jc = javax.xml.bind.JAXBContext.newInstance(Cancel.class);

I'm currently using Axis2 v 1.3.

Thanks in advance for you help,
