When replacing all occurrences of a (syntactically) common subexpression, Eclipse doesn't check whether some of the subexpressions are modified meanwhile in an obvious way.

package de.roland_illig.eclipse.bugs;

public class RefactorCommonExpressions {

  public static void main(String[] args) {
    int i = 1;
    System.out.println(i + 1);
    i++;
    System.out.println(i + 1);
  }
}

When I tell Eclipse to refactor the expression "i + 1", it doesn't notice that i is modified in between. This changes the program output from "2 3" to "2 2".

Reproducible: Always
