Pure Java lstat accepts non-existing files:

jruby -J-Djruby.native.enabled=false -e "p File.lstat('doesnt-exist').size"

But, with native:
jruby -J-Djruby.native.enabled=true -e "p File.lstat('doesnt-exist').size"
-e:1: No such file or directory - No such file or directory - /opt/work/jruby.git/doesnt-exist (Errno::ENOENT)

I commited a partial fix for this, so that if a file/link is totally not there, it will raise an error. It does not, however, fix the case where it should be happy if there's a symlink that points at a non-existent file, where lstat should succeed with no error. Moving to 1.1+ for additional study and work on that case.

Retroactively marking as fixed. There's simply no way from Java to determine that a symlink exists but the file it references does not. We can only go with the simple result that Java gives us. Ultimately, the fix that was in 1.1 is the best we can do for now.
