Java Coding Convention Errors

[Soheil Eizadi]

Looks like in the new trunk we have turned on checks to enforce coding 
conventions in Eclipse? I have errors with some classes that I need to turn off:
"Name 'is_default' must match pattern '^_?[a-zA-Z0-9]*$'."

For example a declaration:

    private boolean is_default;

These classes are part of the interface for REST communication so the strings 
must match the corresponding JSON objects. What is the best practice to turn 
this off in the project for a particular Class?
