Hey

Running JRuby 1.7.25 in a JUnit test (not command line), maven dep:

org.jruby
jruby-complete
1.7.25

no special options, environment variables or gems, just stock JRuby. Running on OSX:

Darwin 15.4.0 Darwin Kernel Version 15.4.0: Fri Feb 26 22:08:05 PST 2016; root:xnu-3248.40.184~3/RELEASE_X86_64 x86_64

Expected Behavior

Expect the test to complete, running YAML.load_file() of an empty file, 10000 times in a row. The test fails earlier with file content, and earlier depending on the amount of content in the file it seems. The test fails for me around iteration 1200-1800. The unit test to show the failure is attached (RunTests.txt)

Actual Behavior

snakeyml throws an IOException at around ~1200-1800th iteration, not exact everytime obviously. Iteration number depends on the size of the YAML being read in (no content in my test to make it easier). This is all done on one thread, so there shouldn't be any concurrency or thread safety issues i'd think.
