In ODE version 1.3.3, replace the jar with the source code, when starting ODE server, an error will generate. java.util.HashMap is not a interface.

I replace the jar with source code, then an error will generate, when starting ODE server, I think the source code do not match the jars which are in the war.

Exception:
HashMap is not an interface.(Occur in the ProcessStoreImpl.java)
