Hello,

Replace method is equivalent to the code snippet:

/if (cache.containsKey(key)) {
   cache.put(key, value);
   return true;
 } else {
   return false;
 }/

Can you lock at the jcache Javadoc:
http://ignite.apache.org/jcache/1.0.0/javadoc/javax/cache/Cache.html#replace(K,
V)
http://ignite.apache.org/jcache/1.0.0/javadoc/javax/cache/Cache.html#put(K,
V)
