I changed line 38 to this to fix the issue:

File.open(marshal_file, 'rb+') do |f|

Sorry for the delay. I don't have time to dig into this but I'm willing to take a patch 'rb+' if it's done just for jruby. I don't want to mess up what was done for #30.

I had this same issue with a unit test in my code. It worked fine with MRI 1.9.3.

File.open(".\test\log\testfile3.log",File::CREAT, 0644) do |f|
f.flock(File::LOCK_EX)

I changed the above to the below and now it works perfectly in both MRI and Jruby.1.7.2

File.open(".\test\log\testfile3.log",'rb+') do |f|
f.flock(File::LOCK_EX)

You've saved me a lot of work and confusion.
Thank you.
