Spring Injection for Strings using Groovy - spring

Question

This example was working and the only thing I think has changed is the version of java and groovy I have installed.
#Grab('org.springframework:spring-context:3.2.1.RELEASE')
#Grab('org.apache.commons:commons-lang3:3.1')
#GrabConfig(systemClassLoader = true)
import org.springframework.context.support.ClassPathXmlApplicationContext
def ctx = new ClassPathXmlApplicationContext("classpath:context.xml")
def su = ctx.getBean('su')
def result = su.swapCase('Fee Fi Fo Fum')
assert result == 'fEE fI fO fUM'
println "result = $result"
Here is the context.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="su" class="org.apache.commons.lang3.StringUtils"/>
<bean id="data" class="java.lang.String"><constructor-arg value="Fee Fi Fo Fum"/></bean>
</beans>
If I comment out the second to the last line of the context file it runs.
This used to work and it does not work now. What am I doing now?
I'm running
Groovy 2.3.0-beta-2
Java 1.8.0_05.
This is the log/trace:

Answer 1

You need at least Spring 4 in order to compile using Java 8.
Announced here: http://docs.spring.io/spring/docs/current/spring-framework-reference/html/new-in-4.0.html
You are using Spring 3.2, you must use Java 7.
