tomee 8 change jaxrs provider

we wanna to change jax rs provider on tomee 8. the default provider is johnzon and we want to change it to jackson fasterxml. this change worked in tomee 7.

1. we change open-ejb file and it's not working.

   cxf.jaxrs.providers = com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider

2. we change system.properties file on tomee/conf but it not worked for me.

   openejb.cxf.jax-rs.providers = com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider
