Multiple hits. You need to make sure that buffer state is valid. Use the isHit method of a buffer (implemented by BufferObserver which is provided by MmuModel). MmuModel can be accessed using the MmuPlugin.getModel method.

public final class MmuPlugin implements Plugin {
  ...

  public static MmuModel getModel() {
    ...
  }
  ...
} 

public interface MmuModel {
  BufferObserver getBufferObserver(String bufferId);
  MemoryDevice getMmuDevice();
  String getStorageDeviceId();
  void setStorageDevice(MemoryDevice device);
}

public interface BufferObserver {
  /**
   * Checks whether the given address causes a hit.
   * 
   * @param address Address to be checked.
   * @return {@code true} if the address causes a hit; {@code false} otherwise.
   */

  boolean isHit(BitVector address);
}

Feature is made available in r5718.
