I was just trying to upgrade my Rails app to Jruby-1.1.5 from 1.1.2.
I get the following error below. I poked around a bit and I think its
related to class reloading in development mode.
I threw in a debug statement in
org.jruby.java.MiniJava.createOldStyleImplClass to see what interface
is duplicate:
createOldStyleImplClass org.jruby.gen.InterfaceImpl46879705 superTypes
[org/aps/eop/hibernate/springtx/TxCallback, org/aps/eop/hibernate/
springtx/TxCallback]
The ruby class implementing that interface is:
class CallbackWrapper #:nodoc: all
include Java::org.aps.eop.hibernate.springtx.TxCallback
def block=(block)
@block = block
end
def execute(tx)
@block.call
end
end
I tried setting config.cache_classes = true and it disappears.
Shall I file a bug?
