PropertyUtils.getPropertyValue - Finding "wrong" getter

[corrspt]

Sure, I can't reproduce locally. Could be something on Heroku. If it happens when I am able to upgrade to a later version, I'll ping again.

Thanks for the work on Katharsis.

Hi,

Could you first update your code to a newer version? The latest is 2.4.1.

java.lang.NoSuchMethodError is thrown when the JVM can't find a class so you should add the dependency explicitly. Maybe maven works different on heroku.

p.s. Katharsis uses a copy of Optional since it is build with Java 7, but that is namespaced.

Hi @ieugen , thanks for pitching in.

Regarding upgrading, I'll try as soon as I can (I'm on a 3G connection with limited transfer speed and limit) but I'm not sure I can do that easily because of using the Play Framework. Since katharsis does not have a direct integration with Play I had to fiddle with the internals to find out how to reply to a request - I have a controller method which instantiates katharsis classes in order to to reply correctly. It's on my plans to upgrade katharsis, but I've had some issues trying to upgrade to version 2.3 I think, so I postponed that.

Anyway, I think I didn't explain my problem very well. This is the method signature I have

import java.util.Optional;

public Optional<FluxCommercialDesignation> getShieldingCapFluxCommercialDesignationTestPiece() {
   //method content
}

So, I'm using java.util.Optional but the error is complaining about com.google.common.base.Optional which I'm not using. It's as it looks at my code like this:

import com.google.common.base.Optional;

public Optional<FluxCommercialDesignation> getShieldingCapFluxCommercialDesignationTestPiece() {
   //method content
}

I did not try to put the method signature with java.util.Optional<> explicitly, so I'm wondering if there could some mistake on Katharsis side that could be mixing up the Optional?

Plese check the Spring or Vertx integration (respective projects). The idea is that you should integrate the Katharsis Dispatcher. A sample [1] is in Vertx.

In that case can we close that issue @corrspt?

Yes, @masterspambot. I reverted the solution to not use Optional, but I'll try to to upgrade Katharsis in the mean time (I'll try to follow the directions from the VertX integration... although I'm not familiar with Spring/VertX I should be able to figure something out).

I'll knock on the door again if I need help, thanks for everything.

I close this issue since it might be more a Heroku problem, not Katharsis. We're using standard Java reflection mechanisms, no dirty hacks :)
