[kepler-dev] Very strange issue with Kepler-1.0/Kepler-2.0 compatibility across actors

[Michal Owsiak]

Hi there,

I have strange issue related to Kepler-2.0. During initialization of the 
actor, I am getting exception (see below).

I have an actor, initially developed for Kepler-1.0.

This is very basic actor. It is based on Image Reader actor.

There are, however few differences. It reads image location from port 
instead of parameter and it reads it within fire method instead of prefire.

This way, file loading can be triggered.

I have attached source code of the actor. Dis is real stopper for us 
during development, thus any help will be highly appreciated.

Exception, I get follows:


java.lang.NoSuchFieldError: OBJECT
