Is this serious GWT err “Somethin other than an int was returned from JSNI method @…”?

I have this error longtime ago but not sure when it happened,

Maybe (BUT NOT SURE 100%) when i do some sort of mouse move & identify the coordinate of widget.

This is the error:

[WARN] - Something other than an int was returned from JSNI method '@com.google.gwt.dom.client.DOMImpl::eventGetClientX(Lcom/google/gwt/dom/client/NativeEvent;)': Rounding double (1239.1300048828125) to int for int

The error is not in Red so i don't think it's serious. Also the system is still running OK so i don't bore until today I suddenly think that:

• "Is a Good / Robust final Gwt app before deployed into Production Product must not contain any kind of error in eClipse?". or "Just don't care a unimportant error as it will be OK?"

I include a picture of this error from my eclipse

Should I bore this error? If I should, then how to fix it?
