Open3.popen3 hangs on windows

Ruby JRuby
1

I’m working on a JRuby application that automates running gems by using
popen3 and found what appears to be a bug.

Using Open3.popen3(‘jruby someGem -v’) hangs JRuby on Windows. On
Ubuntu it works as expected. Is there a workaround for this? I found a
similar issue in JIRA.

Hmm interesting. Completely hangs, as in it never returns? Should be
easy for us to reproduce.

Can you do that, hit Ctrl+Break (to get a thread dump) and add your
dump to that bug please?

I did additional testing and it’s limited to the bundled JRuby in
NetBeans 6.8.

If the same code is run from a direct install of JRuby 1.4.0 then it
works as expected.

Since it works fine when run from the proper environment, it’s likely
not a bug and just an issue of making sure the load path is correct. I
rewrote the application to call into the gems instead of using popen3.

I’ll report it to them and see what they say.

If you feel up to it, you might report it to the NetBeans guys, so
they at least have it in their queue.
