Exception when using ES 1.3.1 Caused by: java.lang.IncompatibleClassChangeError: Implementing class

Elastic Stack Elasticsearch
1

Hello,

I have a project using Play framework version 1.2.7 which used ES 1.1.1.
I wanted to update it to the latest and greatest (1.3.1), but encountered
the following exception when running the unit tests within the play
framework:

An unexpected error occured caused by exception
IncompatibleClassChangeError: Implementing class

(see full trace below)

I'm using Java7 (1.7.0_51).

ES 1.2.3 has no issue, it starts with 1.3.0 to exhibit this problem.

I have looked at the issue and it seems it's caused by not using the right
class version, but I wasn't able to pin point to the exact one.

Has anyone encounter this or know which particular class may introduce this
issue?

Thanks,

Greg

This is a dependency problem. Check your classpath if you have clean
dependencies to ES 1.3.1 code only.

Hey Greg,

I'm facing the same issue:

  • Play 1.2.7
  • Trying to upgrade the embedded ES dependency from 1.0.0 to 1.4.2
  • IncompatibleClassChangeError, identical stack trace
  • Updating to Elasticsearch 1.2.x works

Could you resolve the issue? If so - how? :slight_smile:

Thx,
Stephan
