ReformatTask Context Return 0 for Caret Offset

Hello,
So I have ran into something interesting. On the ReformatTask, the context always returns 0 for caretOffset, i.e. context.caretOffset();

I have tested this against the IndentTask, which does return the correct value. 
Is there a reason for this? I am using NetBeans 8.2.

Thank you,
Trevor
