> In case when {{OFFHEAP_VALUES}} mode is used {{EvictionPolicy}} calculates values size wrongly which leads to the fact that data is evicted only when either the limit on number of entries is reached or size of keys is bigger than max allowed size.
> To reproduce set the following cache configuration
> {noformat}
>         FifoEvictionPolicy plc = new FifoEvictionPolicy();
>         plc.setMaxMemorySize(2 * 1024 * 1024);
>         cacheCfg.setEvictionPolicy(plc);
>         cacheCfg.setMemoryMode(CacheMemoryMode.OFFHEAP_VALUES);
>         cacheCfg.setSwapEnabled(true);
> {noformat}
> Test that reproduces the issue is attached.
> Also attached a patch that fixes the issue. However we should validate that the fix is full and add additional tests to the test suites.
> Finally, {{cache.metrics().getOffHeapAllocatedSize()}} always returns 0 for this cache mode. Has to be fixed as well.
