Java::JavaLang::ArrayIndexOutOfBoundsException: 2 thrown when calling java
method using String...
-------------------------------------------------------------------------------------------------
Key: JRUBY-6010
URL: https://jira.codehaus.org/browse/JRUBY-6010
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.6.3
Environment: Ubuntu 11.04 64bit using JRuby 1.6.3 against Java 6
Reporter: Alex Tambellini
Priority: Minor
I have a method in java with the following method signature:
public Set<Blah> getBlahs(Blah firstBlah, Blah secondBlah, int firstInt, int
secondInt, String... strings)
and I try to call this method from jruby using a single string in the array
using the splat operator:
array_of_strings = ["blah"]
get_blahs(blah, blah, 0, 3, *array_of_strings)
It succeeds.
If I try to call this method from jruby using multiple strings in the array not
using the splat operator:
array_of_strings = ["blah", "blah"]
get_blahs(blah, blah, 0, 3, chain.to_java(:string))
It succeeds.
If I try to call this method from jruby using multiple strings in the array
using the splat operator:
array_of_strings = ["blah", "blah"]
get_blahs(blah, blah, 0, 3, *array_of_strings)
It fails with the following stacktrace:
