Mule Migration from 3.8.4 to 3.9.2 jars related issue

Question

Getting below issue while migration from 3.8.4 to 3.9.2 Mule runtime.

java.lang.NoClassDefFoundError: org/springframework/context/ResourceLoaderAware (org.mule.api.lifecycle.InitialisationException) (org.mule.api.config.ConfigurationException)

I have spring spring-context-4.1.9.RELEASE.jar and all default jars in opt folder of Mule runtime. ResourceLoaderAware class is in this spring-context-4.1.9.RELEASE.jar.

Any idea how do I resolve this issue.

Error NoClassDefFoundError doesn't mean that it was not able to find the class, it means that there was some previous error loading the class. You need to find the previous error to identify the root cause.

It might that there are some incompatible versions in the classpath that caused the original error.
