Could you try reducing the test case?

Ok here are some updates:

  • The error does not appear at the end of the POST, it appears at the beginning of the following request
  • Not all requests will trigger it. Simple ones, such as printing out session info, do not. Following that with a page request will still trigger it.
  • Whether or not the <attribute>_html property is read from the model does not effect the error
  • The error only appears when using the AutoHtmlFor module, which calls auto_html methods automatically. It does not appear when setting the values manually.

Actually, everything I just said is wrong. While testing that, I was using a different set of converters. Predictably, they were to blame.

Passing a block of text through image conversion, even without any image in that text, causes the blowup. And on the same request, too.

Peter, is there any chance you can compile jruby-master (use 'ant clean cext jar' to compile, so it rebuilds the native stub), and test again?

I found one bug related to a NULL dmark function (which recarpet uses), but I'm not sure if that is the reason it is crashing for you, since that is a different error.

FWIW, I think this started showing up for us on OS X (and only on OS X) as of JRuby 1.6.4. 1.6.3 does not have the same issue, so something changed in our cext library.
