Description of problem:
For a mortal entry (lifespan > -1), overwriting it with lifespan=-1 (make it immortal) unexpectedly removes the entry like follows.

~~~
    cache.put(key, "value1", 100, TimeUnit.SECONDS, 100, TimeUnit.SECONDS);
    cache.get(key); // returns "value1"
    cache.put(key, "value2", -1, TimeUnit.SECONDS, 100, TimeUnit.SECONDS);
    cache.get(key); // returns null, expected "value2"
    cache.put(key, "value3", -1, TimeUnit.SECONDS, 100, TimeUnit.SECONDS);
    cache.get(key); // returns "value3"
~~~

In library mode, the 2nd get returns non-null as expected.  The same behaviour is observed for a transient (maxIdle > -1) entry also.


Steps to Reproduce:
1. Start a standalone JDG server.
2. Run the attached reproducer.
