Jruby-1.7.10 - IO.read().size changes after the first access

Hi,

I am using jruby-1.7.10. I am having an issue that I don’t understand.
The
simple following test does not pass on jruby but works well on MRI. Any
idea ?

describe “IO.read” do
it “return the same value twice” do
obj = IO.read(File.join(File.dirname(FILE), “fixtures”,
‘img.jpg’))
obj.size.should eq obj.size
end
end

The first time obj.size returns 314. But after that it returns 311.

Thanks

FYI, the bug is not reproducible when using the BINARY mode.

So in conclusion :

obj = IO.read(File.join(File.dirname(FILE), “fixtures”, ‘img.jpg’),
encoding: ‘UTF-8’)
obj.size # returns 314
obj.size # returns 311

obj = IO.read(File.join(File.dirname(FILE), “fixtures”, ‘img.jpg’),
encoding: ‘BINARY’)
obj.size # returns 314
obj.size # returns 311
