    Description

      SpringCacheTest.java
      public void testPutNullError() {
            //when//then
            cache.put("key", null);
       
            cache.get("key", String.class);
         }
      

      We get

      java.lang.IllegalStateException: Cached value is not of required type [java.lang.String]: org.infinispan.spring.provider.NullValue@76f7d241
      

      JavaDoc for this method states this method does not make difference between cached null and null value.

      Note: This variant of

      {@code get}

      does not allow for differentiating

      between a cached

      {@code null}

      value and no cache entry found at all.

      Use the standard

      {@link #get(Object)}

      variant for that purpose instead.
