Basic spring configuration doesn't work

I wanted to try out basic getting started example with embedded-jmxtrans. So I add the below code
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jmxtrans="http://www.jmxtrans.org/schema/embedded"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.jmxtrans.org/schema/embedded http://www.jmxtrans.org/schema/embedded/jmxtrans-1.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config/>
<jmxtrans:jmxtrans>
<jmxtrans:configuration>classpath:jvmmonitoring/jmxtrans/jmxtrans.json</jmxtrans:configuration>
<jmxtrans:configuration>classpath:org/jmxtrans/embedded/config/tomcat-6.json</jmxtrans:configuration>
<jmxtrans:configuration>classpath:org/jmxtrans/embedded/config/jmxtrans-internals.json</jmxtrans:configuration>
<jmxtrans:configuration>classpath:org/jmxtrans/embedded/config/jvm-sun-hotspot.json</jmxtrans:configuration>
</jmxtrans:jmxtrans>
</beans>public class EmbeddedJMXTrans {
public static void main(String[] args) {
System.setProperty("spring.profiles.active", "dev");
System.setProperty("spring.profiles.default", "dev");
System.setProperty("spring.liveBeansView.mbeanDomain", "dev");
ApplicationContext context = new ClassPathXmlApplicationContext("jvmmonitoring/jmxtrans/spring-beans.xml");
while (true) {
}
}
}The while loop was added to keep the application up till the jvm statistics are printed on console. Here is the jmxtrans.json file
{
"queries": [
{
"objectName": "java.lang:type=Memory",
"resultAlias": "jvm.memory",
"attributes": [
{
"name": "HeapMemoryUsage",
"keys": ["committed", "used"]
},
{
"name": "NonHeapMemoryUsage",
"keys": ["committed", "used"]
}
]
},
{
"objectName": "java.lang:type=Runtime",
"resultAlias": "jvm.runtime",

},

"attributes": [

"ProcessCpuTime",
"SystemLoadAverage"
]
}
],
"outputWriters": [
{
"@class": "org.jmxtrans.embedded.output.ConsoleWriter"
}
]
}On enabling debug level logs I found that jmxtrans spring bean wasn't created because of a spring circular reference error
DEBUG o.s.b.f.s.DefaultListableBeanFactory 1426 - Ignoring bean creation exception on FactoryBean type check: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'jmxtrans': Requested bean is currently in creation: Is there an unresolvable circular reference?
The complete spring logs are shared here - http://pastebin.com/p2VeNEzE
What could be missing?

Hello,
Can you list all the jars that are embedded by your application?
You may have a mix of Spring jars of different versions (2.x, 3.x and 4.x) as show in the logs below.

I verified that the classpath had just spring 4.0.3 jars. I later recreated the sample with minimal spring jars and ran the application. I get the same error in spring debug logs - http://pastebin.com/wD5hKSvg
The spring jars are - spring-aop-4.0.3.RELEASE.jar, spring-beans-4.0.3.RELEASE.jar, spring-context-4.0.3.RELEASE.jar, spring-core-4.0.3.RELEASE.jar and spring-expression-4.0.3.RELEASE.jar

On debugging a bit more I realized that the errors were not of a concern. The issue was because I didn't fetch the bean from the context. After adding the below code, I see a daemon thread printing the jvm metrics on the console every 30 seconds.
Seems to resolve the problem.
