> The default value for {{maxMergeSizeForForcedMerge}} in the class {{LogByteSizeMergePolicy}} is {{Long.MAX_VALUE*1024*1024}} which overflows and becomes -1048576.
> As far as I can see this results in forced merges always failing to merge, but frankly this is so far from my area of interest that I will not take the time to create a proper unit test.
