----------------------------
Summary: StackOverflow when calling java.util.regex.Matcher#end
Key: JRUBY-6571
URL: https://jira.codehaus.org/browse/JRUBY-6571
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.6.7
Environment: java version "1.7.0_02"
Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
Java HotSpot(TM) 64-Bit Server VM (build 22.0-b10, mixed mode)
jruby 1.6.7 (ruby-1.8.7-p357) (2012-02-22 3e82bc8) (Java HotSpot(TM) 64-Bit
Server VM 1.7.0_02) [linux-amd64-java]
Reporter: Kai D
Priority: Minor
{code:ruby}
require "java"
import "java.util.regex.Pattern"
import "java.util.regex.Matcher"
s = "hello world"
r = Pattern.compile("[eo]")
m = r.matcher(s)
while m.find()
puts m.start #=> 1
puts m.end
#=> ArgumentError: wrong number of arguments (0 for 1)
#=> (root) at foo.rb:9
puts m.end(0) #=> StackOverflow
end
{code}
The call of java.util.regex.Matcher#end with no argument throws an illegal
ArgumentError (but java overloads the method with #end() and #end(int)). If I
call the method with one argument, a stack overflow occurs.
