generator-jhipster: Inserts fails with entities having fields named using MySQL reserved words

Using the sub-generator to create entities with fields that are named using MySQL keywords (e.g.: index, group) creates database columns that use those keywords as its names. Performing insert operations using jhispter´s generated Repository fails with hibernate´s SqlExceptionHelper reporting an SQL Exception. In my case:

org.hibernate.engine.jdbc.spi.SqlExceptionHelper - You have an error in your SQL syntax; check the     manual that corresponds to your MySQL server version for the right syntax to use near 'group,

Steps to reproduce:

1. Starting from the example jhipster app that uses a MySQL backend, create a new entity using the yo jhipster:entity subgenerator
2. Add at least one field to that entity named with a MySQL keyword (e.g.: group)
3. Lauch the application and go to to the Entities > [entity name] page and click Create a new [entity name]
4. Fill the form with valid values and click Save.

Result: The operation fails because of an SQL exception. Running the generatad statement in the MySQL terminal fails in the same way unless you surround the offending name with backticks (`).

Using generator-jhipster 2.6.0 package, on Windows 7 MySQL Server version: 5.6.20
