Uploaded Image Corrupted with JRuby 1.7.10

[jimtsay]

For those using JRuby. Image upload may not work with this gem.
Try the following code on JRuby:

f = File.open("test.png")
obj = f.read(f.size)

f.size and obj.size are not the same. It causes content-length and stream size not the same, and image file is corrupted.

With which version(s) of JRuby are you seeing this problem?

[jimtsay]

It's in the title. I didn't try any new version since then.

[sodabrew]

Oh, yes it is. I missed that. Was hoping to that a newer version of JRuby since the issue was filed would have fixed the problem, but don't know.

[jimtsay]

@sodabrew I am not using JRuby for a long time. Are you still seeing this in the latest JRuby? I had a workaround for this issue at that time.

It would be good to make a spec for this to confirm correct behaviour - PR welcome.
