I have an app for processing XML files. I have to pick them up from an inbound directory, parse the XML (using Nokogiri) and make web service calls based on that info. The files are a a collection of orders. After moving the file from the inbound directory, I'm seeing the following error before I can even start parsing the file:

"Unhandled Java exception: java.lang.RuntimeException: Unhandled IOException: java.io.IOException: unhandled errno: File name too long"

In this case, the file name is CD_112350_677686.XML, and I have other JRuby apps that handle files named like this without problem.

Environment

• JRuby version: jruby 1.7.19 (1.9.3p551) 2015-01-29 20786bd on Java HotSpot(TM) 64-Bit Server VM 1.8.0_66-b17 +jit [darwin-x86_64](I've also replicated this on 9.0.4.0)
• OS: Darwin pbdal-whlp2.main.pbd.com 15.5.0 Darwin Kernel Version 15.5.0: Tue Apr 19 18:36:36 PDT 2016; root:xnu-3248.50.21~8/RELEASE_X86_64 x86_64
• Gems: json 1.8.3, rest_client 1.7.3, jdbc-mysql 5.1.38, netrc 0.7.9, nokogiri 1.6.7.2, bundler 1.12.5
• This is a standalone app that once working I plan to compile to a JAR using warbler

Expected Behavior

The file is moved correctly, but I would expect to be able to parse the file and assign each order within to a SalesOrder object. Here's the method where the failure is occurring:
def process_orders_from_file(file_name)
@logger.info("Processing file #{file_name}")
SalesOrders.new(@properties['files']['inbound'] + file_name)
end

Actual Behavior

The call fails immediately after the log entry, with no new SalesOrder objects created.

I have a couple gists with the stack trace - the first was from walking through the code in jirb:

This gist is from when the method is called from within the app actually running:
