Operations Definition into nuxeo-operation-features not correct

• Add the Nuxeo Nature for nuxeo-operation-features
• Try to publish operations defined to a Studio Project

Problem:

• An Exception is thrown (ex: Cannot introspect operation CreateRelation.java
  Cannot extract annotations values in ....)
• Operations are partially published (missing field in SendMail for instance)

Waiting result:

• No Exception and operations well deployed
