Memory leak in InMem DAO
------------------------

                 Key: ODE-639
                 URL: https://issues.apache.org/jira/browse/ODE-639
             Project: ODE
          Issue Type: Bug
          Components: BPEL Runtime
    Affects Versions: 1.3.2
         Environment: any
            Reporter: Rafal Rusin
            Assignee: Rafal Rusin


In Memory DAO, there is a cleanup strategy, which assigns TTL 10 min. for in-memory instances.

I works for 1 in-memory process, but for 2 or more, there are cases when it doesn't do cleanup.

I figured out that cleaning strategy in bpel-runtime/src/main/java/org/apache/ode/bpel/memdao/ProcessDaoImpl.java
holds a static _lastRemoval field, which is updated globally. But if there are >1 in-mem
processes, it may cause only one to do cleanup. 

A simple patch, which removes static declaration solves problem, because then, cleanup is
done separately for each process.
