<p>I want to force the current execution line to a specific line in the same function, possibly skipping intermediate lines. All my old school debuggers had this feature, but I can't find it in eclipse. Is there a way to do it without changing code?</p>

"Run to line" appears to need the program to be running and in a paused state to use.  The other option is to set a breakpoint for that line when running in debug-mode.
Double-click far-left vertical bar in the source pane on the same line to add a breakpoint; or,
Select the line and go to Run > Toggle Breakpoint.
At least, this is in Eclipse 3.3.2.
