This seems this error:

https://pharo.fogbugz.com/f/cases/19227/Writing-a-File-with-a-relative-path-to-the-working-directory-results-in-FileException-cannot-open-file

and this is caused by it, too.

I wonder why we do not use FileSystem for all these file related operations?

Hi All,

I'm porting (no big changes) code from pharo 4 to pharo5.

In (*) the resulting file handle is nil. Not sure why, may it be something related to the recent Mac OS X upgrade �to Sierra?

The same code was working with Pharo 4 on El Capitan.

The calling code is a Fuel serialization.

openForWrite: writeMode�

"Open the file with the given name. If writeMode is true, allow writing, otherwise open the file in read-only mode."

| fileHandle |

(*) fileHandle := self basicOpenForWrite: writeMode.

fileHandle ifNil: [ FileException signal: 'cannot open file: ', name ].

^ (BinaryFileStream handle: fileHandle file: self forWrite: writeMode)

register;

yourself

any advice is welcome.
