Title: Remove redundant file.close

While profiling "assets:precompile" under JRuby, I came across this call to `File#close` that is redundant but results in an exception under the hood. Getting Java stack trace data is somewhat slow in JRuby, so this is a performance issue.

I successfully ran the unit tests with `rake test` using JRuby 1.7.0 in 1.8.7 compatibility mode.
