Thanks for the info but it doesn't help.

I add a context.xml with :
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/my-jbpm-webapp">
  <Manager pathname=""/>
</Context>

And it doesn't change anything...

The only workaround (heavy !) is :
* undeploy from tomcat,
* restart tomcat,
* redeploy the application...
It's not really a good solution, but I can continue to work ahead, before finding for a better solution !

The thread you point is interesting, but I'm not using jbpm installation tools, i'm using maven to build.
My theory is jbpm stay loaded when trying to redeploy so the new classloader is in conflic with the previously loaded one...

There is a background task launching an hibernate session regularly as I see some SQL request launch every 2 au 3 seconds :

I suspect that thread to never been stopped so the old classloader is never dereferenced ...

Is there a possibility to end that thread (with an application listener for example) ?
