Description

IO.sysopen('/tmp') -->
Errno::ENOENT: No such file or directory - /tmp

While it works just fine on MRI.

This also fails one rubyspec:

jruby -S mspec core/io/sysopen_spec.rb
jruby 1.5.0dev (ruby 1.8.7 patchlevel 174) (2009-10-02 853e083) (Java HotSpot(TM) Client VM 1.6.0_03) [i386-java]
.E..

Limitation of Java's file APIs...we can't open a directory. We'd have to emulate libc's treatment of opening directories as files or else wrap a native call. Ugly, either way.

Ugly, but we can make a RubyDirFile.java which extend RubyFile and construct an instance of this on a directory entry (from open or wherever else) we should be able to be compatible enough with MRI. As far as I can tell opened directories only works with operations like: fd, stat, unlink, and chown. Everything else may throw ES_ISDIR.

Got bitten, commenting so I get notifications about updates.

Using the TMPDIR workaround from JRUBY-5678 is working for me for now.
