JRuby 1.5.2 and Glassfish gem don't play well together

I upgraded from 1.5.1 to 1.5.2 and started getting the following
exception

It happens using the Glassfish gem 1.0.2 but not using WEBrick. I
reverted
to 1.5.1 and it definitely stopped occurring. I’m using Rails 2.3.2.

Hi all!

I am having the same problem. Any tip on how to debug this one?

Have you filed a JIRA issue for this?

Is there a simple app that reproduces this problem? I have been working
on the gem.

I didn’t file a JIRA as I’m not sure the underlying problem is caused by
JRuby, glassfish or something else. For now, we’re sticking with 1.5.1.
I
did run a dev version of 1.5.2 on our production box (for investigation
of
http://jira.codehaus.org/browse/JRUBY-5018) and it didn’t have this
problem.

I am having a very similar error, but in a slightly different place. I
also
have Neo4j setup and see the error when doing a post. I turned off
logging
and the problem went away. It was worse with Rails threading enabled,
happened with every multi-part form post.

Sorry I don’t have a test app yet.

Hi

I have the same problem.
It works with JRuby version 1.5.1 but not with 1.5.2 and 1.5.3.
In my rails application it seems to be related to using the Neo4j java
library (http://neo4j.org/)
If I don’t use the graph database I can’t reproduce the error.

I have written a little rackup program to reproduce the bug.
http://old.nabble.com/file/p29846519/glassfish-jruby-bug.tar.gz
glassfish-jruby-bug.tar.gz

Looks like a problem when writing to the database as the same time as a
POST
request is received.
(Hopefully it is the same bug as I get in my rails application.)

  1. Create a log folder: mkdir log

  2. Start the rackup config.ru script type: glassfish
    The script will starts a thread writing 10000 nodes to the database
    using
    the neo4j database.

  3. Then quickly do some POST, type:

for i in {1…10}; do curl -d “param1=value1&param2=value2”
http://localhost:3000; done

You will now get a 500 server error.
probably because writing to the database and POST request happend at the
same time.

Cheers
Andreas
