Chapter 4 Spring Expression Language (SpEL), section 4.3.9. Constructors of official documentation contains incorrect description of default behavior. According to source code of org.springframework.expression.spel.support.StandardEvaluationContext there is a use of org.springframework.expression.spel.support.StandardTypeLocator class. According to the source code of letter class the core package 'java.lang' is registered by default.
