PassiveExpiringMap doesn't work when the key is a byte array

When you put a (key,value) pair in a PassiveExpiringMap and the key is byte[] you can't retrieve it.

Code to reproduce the problem:

byte[] key =

{0,0,0,1};
PassiveExpiringMap<byte[],byte[]> map = new PassiveExpiringMap<byte[],byte[]> ();
map.put(key,key);

byte[] queryKey = {0,0,0,1}

;
//this should be true
map.containsKey(queryKey) == false
