properly detect JDK 1.6/1.7 (Java 6/7) as higher than 1.5 (Java 5) * fixed SpringVersion to return null if the package is not determinable because of ClassLoader restrictions * fixed PathMatchingResourcePatternResolver warn logs for acceptable conditions * JdbcTemplate uses "PreparedStatement.setObject(index, null)" for null values with unknown SQL type on Informix * JdbcTemplate by default uses "PreparedStatement.setString" constract details * CharacterEncodingFilter only applies its encoding if actually specified (non- null) * WebDataBinder explicitly suppresses field marker prefix values in case of "ignoreUnknownFields"

Package org.springframework.aop * AbstractAutoProxyCreator (as used by "aop:config") correctly ignores null bean instances * "aop:aspect" doesn't insist on aspect bean reference to be specified when just SmartInstantiationAwareBeanPostProcessor's "determineCandidateConstructors" is only invoked for non-null bean Class * ServiceLocatorFactoryBean handles equals and hashCode based on proxy object identity a generic superclass method * @ModelAttribute annotated handler method arguments can resolve to a null value as well (when contained in the model) * standard method argument subtypes (such as a Principal

bean instantiation failure * fixed BeanWrapperImpl to convert a null input for an array type to a null value rather than an array with null element * changed MutablePropertyValues's "addPropertyValue" signature remain binary compatible with Spring <=1.2.6 * fixed BeanArrayPropertyEditor to translate null value to null byte array * added CharArrayPropertyEditor to translate String value into char array * CharacterEditor defined in child Package org.springframework.core * refined NestedXxxException to properly handle null message in root cause, through using the cause's "toString()" * fixed FileSystemResource/UrlResource

Package org.springframework.beans * CharacterEditor's "allowEmpty" only translates empty String to null, keeping a single space String as space character * CustomNumberEditor treats number with leading ClassLoader explicitly excludes types to match (for OSGi LTW compatibility) * restored support for null location array argument in ClassPathXmlApplicationContext (for Apache CXF compatibility) * added ENC names by default) * NativeJdbcExtractorAdapter only processes DatabaseMetaData Connection if non-null (for WebLogic cluster compatibility) * fixed SQLException translation for IBM DB2 and MS SQL to operate
