Description

In Procedure#toStringDetails() :

    if (stackIndexes != null) {
      sb.append("\n");
      sb.append("stackIndexes=");
      sb.append(Arrays.toString(getStackIndexes()));
    }

The access is not protected by synchronized keyword whereas access to stackIndexes is protected in all other methods.

Note: getStackIndexes() has proper protection.
