OpenOptions on newInputStream.

[Salter, Thomas A]

FileSystemProvider.newInputStream disallows any OpenOption other than StandardOpenOption.Read.   Thus it can't be used to specify a LinkOption or an implementation-defined extension.  Was this really the intention?

FileSystemProvider.newOutputStream, on the other hand, explicitly disallows StandardOpenOption.Read but allows everything else.

I can fix this by overriding the FileSystemProvider implementation in my provider, but it doesn't seem like I should have to do that.


On a related note, there seems to be a lack of completeness with the various shortcuts for opening files:

1.      Files.newBufferedReader does not take open options, but Files.newBufferedWriter does.

2.      Files.newByteChannel takes a FileAttribute parameter, but Files.newBufferedWriter and newOutputStream do not, even though all can create files.
