> LocalDirAllocator.AllocatorPerContext.confChanged() accesses conf.get() twice unnecessarily. The 2 calls can give 2 different values, which can lead to issues because the first call's return value is saved in savedLocalDirs and is used for comparison in the next call to confChanged() method --- So the comparison is wrong.
