Not sure if it is harmless, but it can be suppressed by disabling JavaScript Validator from project preferences Properties->Builder. Project error markers then can be deleted manually from Problems or Markers Views. Then clean/rebuild for project should not report any javascript problems.

It seems JSDT has problems to parse java script with switch statement like this one

{code}switch ( event.keyCode ) {
   case $.mobile.keyCode.HOME:
   case $.mobile.keyCode.END:
   case $.mobile.keyCode.PAGE_UP:
   case $.mobile.keyCode.PAGE_DOWN:
   case $.mobile.keyCode.UP:
   case $.mobile.keyCode.RIGHT:
   case $.mobile.keyCode.DOWN:
   case $.mobile.keyCode.LEFT:
	event.preventDefault();
	if ( !self._keySliding ) {
	    self._keySliding = true;
            $( this ).addClass( "ui-state-active" );
	}
   break;
}{code}
