File.flock does not work on Solaris for 9k #3343
Description
Same issue reported for 3254. The code change fixed the 1.7 branch (1.7.22) but issue is still in 9k. I thought it would be in 9.0.1.0 since it was released after:
$ ./jruby --version

$ ./jruby -e "File.open('/tmp/test', File::RDWR|File::CREAT) { |f| f.flock(File::LOCK_EX) }"
