Calling interface method on specific instance from Java doesn't work.
---------------------------------------------------------------------
Key: JRUBY-2927
URL: http://jira.codehaus.org/browse/JRUBY-2927
Project: JRuby
Issue Type: Bug
Components: Java Integration
Reporter: Ola Bini
Assignee: Ola Bini
Priority: Critical
Fix For: JRuby 1.1.4
Since the Java Integration work, Java calling into specific interface
implementations on a custom object doesn't seem to work anymore. The behavior
can be easily seen with the HashMap constructor, which will take a Map argument
and call size() on it:
{noformat}
class AMap
include java.util.Map
end
obj = AMap.new
def obj.size
0
end
java.util.HashMap.new(obj)
{noformat}
This will currently fail with a NoMethodError for size, which is incorrect.
This problem makes all kinds of mocking and stubbing on Java instances
impossible. I'm currently in the process of committing a failing spec for this
behavior, and a fix should be forthcoming.
