How to remove 'Assignment of Parameter 'variable' is not allowed'

I'm programming a Controller using Java and I'm checking the style using Sonar. In my Sonar I have an error that says:

'Assignment of Parameter 'variable' is not allowed.

The line that it's on is:

@RequestParam(value="variable", required=false) String variable

So I'm wondering how I could get that error off since I can't just create a setter when I'm using that annotation.

EDIT

I'm using Eclipse. The rule being broke is Parameter Assignment.

@RequestParam(value="variable", required=false) String variable
if (variable != null && variable.compareTo("") == 0) {
    variable = null;
}

In your if condition block, you are setting variable to null and it happens to be your method parameter. Instead of assigning the value to the method parameter, create a local variable and use it and return the value of the local variable from the method if at all it is intended.
