Large number of StandardEnvironment objects are initialised during startup. Visible in the logs at DEBUG level. [SPR-10568]

When creating an application context, these log lines are output at DEBUG level many tens of times. It seems that there are an excess of StandardEnvironment objects being created.

This seems to be due to ResourceEditor and ResourceArrayPropertyEditor instances creating a default StandardEnvironment instance, even if usually overridden right afterwards with the ApplicationContext's Environment. AbstractBeanDefinitionReader (and hence the commonly applied XmlBeanDefinitionReader) happens to create such an useless default StandardEnvironment instance as well. I'll try to get rid of those, either using the overridden Environment right away or using a more minimal default PropertyResolver.
