------------------------------------------------------------
Key: JRUBY-987
URL: http://jira.codehaus.org/browse/JRUBY-987
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.0.0RC2
Environment: Linux alpha 2.6.17-10-386 #2 Fri Oct 13 18:41:40 UTC 2006
i686 GNU/Linux
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode, sharing)
Reporter: Rickard Bäckman
I'm using jruby for implementing java interfaces in the code and from time to
time I get a "too few arguments (2 of 3)" or similiar.
I tried to convert one of these ruby methods to
def method(*args)
raise "Arguments is #{args.size}" unless args.size == 3
...
end
and got this:
org.jruby.exceptions.RaiseException
product.rb:38:in `readCategoryPrices': ERROR arguments: 2 (RuntimeError)

It doesn't happen every time and the java code utilizes a couple of threads
which makes calls to the ruby implemented java interfaces. The method is only
called through java (and always with 3 arguments?).
