nil implicitly casts to java.lang.Integer instead of java.lang.Long during
method dispatch
------------------------------------------------------------------------------------------
Key: JRUBY-4038
URL: http://jira.codehaus.org/browse/JRUBY-4038
Project: JRuby
Issue Type: Bug
Components: Interpreter
Affects Versions: JRuby 1.4.0RC1
Environment: Ubuntu linux
Reporter: Greg Fodor
Attachments: bug1.tar.gz
If you have a Java method which receives a parameter of java.lang.Long, in
JRuby 1.4.0RC1 it will cast Fixnums to Integers and also cast nil's to Integers
as well when calling that method from JRuby. The attached example creates a
class with a simple constructor receiving a Long, and the rb file tries to call
the constructor passing nil. It is impossible to call this constructor with nil
because JRuby will always try to pass an Integer.
