This is principally for making Java integration produce more idomatic Ruby. This allows users to configure a class to store specific ivars in a field of a reified class.

I have confirmed this will be green once merged with my Logger test fixes: https://github.com/jruby/jruby/actions/runs/2022952391 However I can't figure out why this example does not work... where is the field? This seems to mimic the (working) specs so I must be doing something wrong here. Once I understand what I'm doing wrong, this is ready to merge. |

There was a problem hiding this comment.
Changes are approved, but I need an explanation for why my naive example is not working.

I always run into this too: any usage of the methods that are shared between irb(main):001:0> class Foo < java.lang.Object; java_field "java.lang.String stringField"; end; f = Foo.new; puts f.class.java_class.declared_fields.to_a
private final org.jruby.java.proxies.ConcreteJavaProxy rubyobj.Foo.this$rubyObject
private static final org.jruby.javasupport.proxy.JavaProxyClass rubyobj.Foo.this$rubyProxyClass
private static final org.jruby.javasupport.Java$JCtorCache rubyobj.Foo.this$rubyCtorCache
private static final org.jruby.Ruby rubyobj.Foo.ruby
private static final org.jruby.RubyClass rubyobj.Foo.rubyClass
=> nil
irb(main):002:0> require 'jruby/core_ext'
=> true
irb(main):003:0> class Foo2 < java.lang.Object; java_field "java.lang.String stringField"; end; f = Foo2.new; puts f.class.java_class.declared_fields.to_a
private final org.jruby.java.proxies.ConcreteJavaProxy rubyobj.Foo2.this$rubyObject
private static final org.jruby.javasupport.proxy.JavaProxyClass rubyobj.Foo2.this$rubyProxyClass
private static final org.jruby.javasupport.Java$JCtorCache rubyobj.Foo2.this$rubyCtorCache
private static final org.jruby.Ruby rubyobj.Foo2.ruby
private static final org.jruby.RubyClass rubyobj.Foo2.rubyClass
public java.lang.String rubyobj.Foo2.stringField
=> nil

@byteit101 Oh boy, that does fix it. Ok, we should do something better than that in the future, but that's not your bug. Let's merge this! |
