Hi Guillaume, as far as I can tell stepping through the code, the exception is
swallowed and logged in SftpSubsystem.java lines 372-375:
} catch (Throwable t) {
if (!closed && !(t instanceof EOFException)) { // Ignore han
log.error("Exception caught in SFTP subsystem", t);
}
} finally {
This is in the public SftpSubsystem#run() method. The stacktrace is like this,
my exception trickles up and is caught in the run() method.
SftpSubsystem.run()
SftpSubsystem.process()
FileSystemView.getFile()

I think the message on the exception is sent back to the user, but currently
there's no way to return a different error code than SSH_FX_FAILURE.
I suppose we could define an exception containing the error code and use it
if such an exception is caught.
