MergedBeanDefinitionPostProcessors apply after all other post-processors (for @PostConstruct to be invoked after other BPPs; SPR-6066)

+ minor improvements to the LTW files (mainly trailing blank lines)

AnnotationMetadata returns Class values by default (again), allowing for explicit retrieval of String class names where preferred (SPR-5827)

SPR-6308 - Spring Expression Language creates systemProperties bean calling System.getProperties() which in enterprise shared containers is locked down
