NullPointerException when performing operations on an IgniteCache
Hey guys!
We discovered that a NullPointerException is thrown by Ignite when trying to perform operations on cache1 in the following code snippet.
CacheConfiguration<UUID, UUID> cache1Config = new CacheConfiguration<>("cache1");
cache1Config.setGroupName("myCacheGroup");
CacheConfiguration<UUID, UUID> cache2Config = new CacheConfiguration<>("cache2");
cache2Config.setGroupName("myCacheGroup");
IgniteConfiguration cfg = new IgniteConfiguration();
Ignite ignite = Ignition.start(cfg);
IgniteCache<UUID, UUID> cache1 = ignite.getOrCreateCache(cache1Config);
IgniteCache<UUID, UUID> cache2 = ignite.getOrCreateCache(cache2Config);
cache2.registerCacheEntryListener(new CacheEntryListenerConfigImpl());
cache2.destroy();
cache1.put(UUID.randomUUID(), UUID.randomUUID()); // throws NPE
System.out.println("meep moop");
CacheEntryListenerConfigImpl is a bare minimum implementation, nothing fancy.
public class CacheEntryListenerConfigImpl implements CacheEntryListenerConfiguration<UUID, UUID> {
@Override
public Factory<CacheEntryListener<? super UUID, ? super UUID>> getCacheEntryListenerFactory() {
return () -> (CacheEntryCreatedListener<UUID, UUID>) iterable -> System.out.println("henlo");
}
@Override
public boolean isOldValueRequired() {
return true;
}
@Override
public Factory<CacheEntryEventFilter<? super UUID, ? super UUID>> getCacheEntryEventFilterFactory() {
return null;
}
@Override
public boolean isSynchronous() {
return true;
}
}
The full exception is as follows.

Hello @coolkarniomkar , Please note that cache2.destroy(); will also destroy cache1 as per the internal referencing due to CacheEntryListener Registration, either destroy the cache later or recreate the cache1 after you destroy the cache2. - Thanks!
