String#sum with negative argument causes NativeException
--------------------------------------------------------
Key: JRUBY-1010
URL: http://jira.codehaus.org/browse/JRUBY-1010
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.0.0RC2
Environment: Windows XP, Java 1.6
Reporter: Daniel Berger
Priority: Minor
String#sum with a negative argument appears to be legitimate. JRuby raises an
ugly NativeException. Just try "hello".sum(-1) or any similar test to see what
I mean:
NativeException: java.lang.ArithmeticException: / by zero
