Re: [jruby-user] Re: Differences Between MyClass.class and getClass() in JRuby

I’m getting the expected result. Using Rsense <http://rsense.github.io/> as
an example:

require "rsense-core"
Java::org.cx4a.rsense.typing::Graph.java_class#=> class
org.cx4a.rsense.typing.Graph

graph = Java::org.cx4a.rsense.typing::Graph.new#=>
#<Java::OrgCx4aRsenseTyping::Graph:0x6d79d6d1>

graph.java_class#=> class org.cx4a.rsense.typing.Graph

graph.get_class#=> class org.cx4a.rsense.typing.Graph

Can you share some example code that produces the result your getting
above? Also, I’m running this on JRuby 1.7.12 on Java 7, is it possible you
are running an older version of JRuby, or perhaps the development version,
JRuby?
