This is something we rarely do. So, nobody bothered to do this. 
And as long as this being static, it doesn't help anyway.

About your question, I vaguely remember there being a difference
::= and ->. I and Manoj discussed this but I don't recall what the difference was.

Regards,
Jay

I also forgot to ask what the rationale behind making the DEBUG field final is? The compiler optimising the 'if (DEBUG)' statements? While trying to solve my issue, it would have bveen nice to be able to set the flag dynamically instead of having to recompile JDT Core.
