The spring3 includes some beans with type java.util.Map. When the autowire of ObjectDescriptor is true, The ObjectDescriptor will try to find related bean by field type. When a component have fields with type java.util.Map. The ObjectDescriptor will get these beans from spring3 and set them as field value.

For example, RepositoryCacheImpl have two Map fields: deployments and deploymentClassLoaders. And RepositoryCacheBinding use autowire to configure it. So when we use jBPM with spring3. The deployments field in RepositoryCacheImpl will be auto set value like this:

And it will cause java.lang.NumberFormatException: For input string: "sun.io.unicode.encoding".

We could change ObjectDescriptor to ignore autowire java.util.Map. Or we could change the SpringContext, when jBPM4 want to get java.util.Map, it should return null.
