Answer 1

Update for those moving to versions above 3.1.x ... as made clear by this answer here there is no longer a separate spring-asm, so it would be better to exclude spring-asm altogether, once you're at Spring version 3.2.x

Answer 2

This error usually shows up when incomptiable versions of jars are used, for example spring-asm and spring-core. Have a look at forum.springsource.org/showthread.php?133341

Answer 3

In spring version > 3.2.0, you no longer need to explicitly include spring-asm since it has already been included in spring-core.

Remove spring-asm from your build definition and ensure that spring-core is there.

Answer 4

This error happens when the loaded class i.e. ClassMetadataReadingVisitor does not respect the contract of inherited abstract class or interface i.e. ClassVisitor.

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.

Answer 5

I had the same problem and faced it by deleting my spring-data-jpa dependency from pom.xml

It's already included in the spring-core dependency.
