Invoking private/protected java no-args method with null argument leads to NPE
------------------------------------------------------------------------------
Key: JRUBY-4599
URL: http://jira.codehaus.org/browse/JRUBY-4599
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.4
Reporter: Vladimir Sizikov
We have java integration specs for that, but the failures were hidden by RSpec
1.2.9 bug. Upgrade to 1.3.0 to see the crashes.
Alternatively, here's the standalone example (it assumes that the file is in
the root of JRuby repo and jruby-test-classes.jar is already build via ant spec
or similar):
{code}
require 'java'
require File.dirname(__FILE__) + '/build/jruby-test-classes.jar'
import 'java_integration.fixtures.PackageStaticMethod'
method = PackageStaticMethod.java_class.declared_method_smart
:thePackageScopeMethod
method.accessible = true
method.invoke Java.ruby_to_java(nil)
{code}
{noformat}
jruby spec-t.rb
JavaMethod.java:232:in `invoke': java.lang.NullPointerException
