I have built a web application using spring-mvc and mongodb as database. I used maven3 to build the application.
Project builds successfully but when application starts I am getting the following error in the logs due to which my application does not start. This used to work few months ago.
Caused by: java.lang.IncompatibleClassChangeError: class
has interface org.springframework.asm.ClassVisitor as super class
This error happens when the loaded class i.e.
ClassMetadataReadingVisitor does not respect the contract of inherited abstract class or interface i.e.
Looks like at load time different versions of the above classes are getting loaded in your case.
Seems you have new spring-core jar and old spring-asm jar in your application.
ClassMetadataReadingVisitor class is getting loaded from spring-core and
ClassVisitor from spring-asm.
Please check using maven
dependency:tree command to see the dependent jars.
