Can Ignite.getOrCreateCache(CacheConfiguration) return null ?

["HEWA WIDANA GAMAGE, SUBASH" <Su...@fmr.com>]

Hi all,
Is there any possibility for this to happen ? We're using Ignite 1.9.0

Following is the code we use to obtain the cache. And we call this line for every cache operation(unintentionally), but wanted to know if following line can return a null cache instance under any circumstance.

Cache<String, String> cache = getOrCreateCache(CACHE_NAME,CreatedExpiryPolicy.factoryOf(new Duration(TimeUnit.SECONDS, 300)));

Sorry, my bad. Here’s the method. Basically I am directly invoking the Ignition.ignite() with expiry policy.

public static <K, V> Cache<K, V> getOrCreateCache(String name, Factory factory) {
    CacheConfiguration<K, V> cc = newCacheConfig(name);
    cc.setExpiryPolicyFactory(factory);
    cc.setStatisticsEnabled(true);
    return Ignition.ignite().<K, V>getOrCreateCache(cc);
}

What does the getOrCreateCache method do internally?

What does the *getOrCreateCache* method do internally?
