Description
When plugin code creates a cache in a clustered environment with replicateAsynchronously() setting, a NPE is thrown. Strangely through, the second call succeeds and the cache can be used.
The code:
CacheSettings settings = new CacheSettingsBuilder().replicateAsynchronously().build();
cacheManager.getCache(cacheID, new MyLoader(), settings);
If replicateAsynchronously() is removed, everything works on the first time too.
The exception:
Exception in thread "ItemTrackerMonitor" java.lang.NullPointerException
