Cannot redeclare class doctrine\orm\mapping\annotation

I am having this really weird issue, and I am not sure if it is an issue with JMSSerializerBundle or Symfony.

I used the built in FormErrorHandler class and it outputted fine. However, I wanted to change the format of the output, so decided to write my own.

So I went into my services and added the new class

    jms_serializer.form_error_handler:
        class: MyCompany\MyBundleBundle\Services\FormErrorHandler

When running with the new class (clearing cache and everything) I kept getting error
Cannot redeclare class doctrine\orm\mapping\annotation

I tried debugging it but coulodn't figure out source of issue.

I then when into
JMS\SerialzierBundle\Resources\config\services.xml and replaced the form error handler class in that file with the new one, and then it worked fine with no exception

I had a custom FormErrorHandler in another project that worked fine using my above setup, but implementing it on this new project doesn't work. I may be running a new version of JMSSerializerBundle than my other project.

I thought maybe an issue with overwriting the service but I completely removed parameter key from the JMS config but still same issue.

As a temporary fix I will change the class in the JMS config, but don't like this option as if it gets upgraded then I will need to make the change again. Anyone have any ideas?

Well I found another solution
In the parameters.yml file I added

jms_serializer.form_error_handler.class: MyCompany\MyBundle\Services\FormErrorHandler

And that worked.

Still curious what is wrong with the first solution but oh well
