Calls of Java methods have stubs to the interpreter for the cases when an invoked Java method is not compiled. Calls of static Java methods and final Java methods have statically bound information about a callee during compilation. C1 and C2 always generate a new stub for each call. As the generated stubs for calls of the same method are  the same, they can be shared.

The following Test.java reproduces the issue: two stubs to the interpreter for calls of the static `error`.

class Test {
  private static void error(int i, String msg) {
    if (i > 900000)
      throw new RuntimeException(msg);
  }

  public static void test(int i, String[] args) {
    if (i % args.length == 0) {
      error(i, "args[0] == " + args[0]);
    } else {
      error(i, "No args");
    }
  }

  public static void main(String[] args) {
    for (int i = 1; i < 1000000; ++i) {
      test(i, args);
    }
  }
}
