Batch Admin webapp hot deployment

[mob]

Hello,

When reloading my batch admin webapp it seems like objects do not get removed. After a couple of reloads out of memory occurs. I have created a new batch admin web app from within STS (using the original spring project template). Set the following spring project versions in my parent pom:
<spring.batch.version>2.1.5.RELEASE</spring.batch.version>
<spring.batch.admin.version>1.2.0.RELEASE</spring.batch.admin.version>
<spring.framework.version>3.0.5.RELEASE</spring.framework.version>
<spring.integration.version>2.0.4.RELEASE</spring.integration.version>
and ehcache:
<ehcache.version>2.4.2</ehcache.version>

Once after some small fixes the project compiled, I launched an sts tc instance with the batch admin webapp under profiling. Following a hot redeploy I observed multiplication of object instances (e.g. DefaultListableBeanFactory)

Are there some suggestions how to properly remove objects when redeploying the batch admin webapp ?

thanks.

In retrospect let me add something that could make answering to my request more feasible:
I would be happy with a sample batch webapp project that can be cleanly reloaded in the app server, to start from.

thanks.
