Artsiom Panko commented on IGNITE-12315:
----------------------------------------
[~alapin], getting <null> is not cool, but what exactly needs to be done?
Replace all "ArrayBlockingQueue" to "ArrayList or LinkedList"?
Or create a custom method which will enable to get cache value via
ArrayBlockingQueue as key?
> In case of using ArrayBlockingQueue as key, cache.get() returns null.
