* action here (from 3 uses of the method, BreakpointIconRenderrer is suspicious, others are inside read).
* It's not smart to take read action here (using breakpoint.getProject()) as well, as SNode return value outside of read action
* makes little sense.
* Please revisit uses of the method and fix them to use SNodeReference instead (expose getPosition() then).
