Jackson throwing errors


Looks like you have many versions of jackson jars and your class path refers some Jackson jar prior to 2.6 at runtime.

Class ResolvedType introduced isReferenceType() from version 2.6 onwards. Please refer link below:

Please ensure you refer the right version or a higher one at runtime. You may remove/delete the older Jackson jars if not required.

Hope this helps.


The latest version of storm is having jackson-core-2.3.1.jar in its lib folder and my fat jar that i create using maven is having another version of jackson dependencies. That is why when i submit my jar in storm cluster it is throwing these No such method errors at run-time..

I changed My POM to use the same version of jackson dependencies what storm is using and everything is working fine.


This Issue seems to come from multiple versions of jackson classes in the classpath. You may remove the unwanted versions off. As of this writing. The current version for jackson isis 2.7.1.
