Stackoverflow when calling code from java with wrong parameters
---------------------------------------------------------------
Key: JRUBY-4788
URL: http://jira.codehaus.org/browse/JRUBY-4788
Project: JRuby
Issue Type: Bug
Components: Application Error, Java Integration
Affects Versions: JRuby 1.4
Environment: OS X 10.6
Java 1.6
JRuby 1.5.0RC3 (tested on 1.4.0 as well)
Reporter: Reto Schüttel
When calling ruby code from java I get strange stack overflow errors when the
arguments dont match. I was able to create an example of that problem, but I
got bigger than I hoped.
What it does is:
1. in ruby start a background thread (implemented java)
2. define and instantiate a 'factory' in ruby. The factory extends a abstract
java factory
3. hand over the factory to the java background class which uses it to create
a 'job' object
4. the job is implemented in ruby, but uses an abstract java job class as a
base class
5. the background thread now executes a method doJob(DbSesssion) on the 'ruby'
job object.
=> at this point a simple error should occur because the signature of the ruby
method doesn't match the abstract method. But instead jruby creates a huge
stackoverflow.
You can find a full working example on github:

the full stacktrace is on:
http://gist.github.com/398349
I'm sure the example could be further simplified, but I don't have much more
time for that right now.
