RubyArray doesn't have toJava method which makes JavaEmbedUtils.rubyToJava fail
-------------------------------------------------------------------------------
Key: JRUBY-4515
URL: http://jira.codehaus.org/browse/JRUBY-4515
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.5
Reporter: Yoko Harada
Attachments: RubyArray.patch, RubyArrayToJavaSample.java
Since RubyArray doesn't have toJava() method, RubyBasicObject.toJava() is used
when JavaEmbedUtils.rubyToJava() method is called against RubyArray. If target
type is java.util.List, the conversion has been successfully performed.
However, when String[] is the target type, conversion fails and RubyArray is
returned without any conversion.
Attached patch resolves the problem and returns correct type for both String[]
and List.
Charlie told me on IRC that KernalJavaAddons.to_java was the answer, but for
some reasons, the method could not be used in RubyArray. Instead, I defined new
toJava() method. This is similar to JavaClass.javaArrayFromRubyArray(), but a
specific target type can be applied to conversion.
