Possible duplicate of SpelEvaluationException: EL1007E:(pos 43): Field or property 'group' cannot be found on null and spring @Cacheable with Ehcache, spel find null for valid object – I believe you compile without debug information. Please check your Maven configuration; you might want to post the relevant bits here. Search your POM (or parent POM) for the maven-compiler-plugin and a line such as:

<debug>false</debug>
