Java. No local filesystem access? Why not? Security, they say. The local filesystem has no sufficient security by default. Of course not. And of course you’re not supposed to be storing private data in the local file system. And if it is private, there shouldn’t be all that much to loose. After all, the file system is supposed to be a small partition. Big data should be delegated to large partitions.
True, but the imprecision of how people use computers results in this not being the case.
