Java - ClassCastException to the very same Class/Package

I am trying to get the Class type received in a response and suddenly I get this exception:

java.lang.ClassCastException: com.myweb.process.api.util.MyProcessModel 
cannot be cast to com.myweb.process.api.util.MyProcessModel

How is this possible?

Would this have something to do with the Classpath?

The code I am running is:

List<Object> responses = context.getResponses();
for (Object response : responses) {
   if (response instanceof MyProcessModel) {
      MyProcessModel model = (MyProcessModel) response;
      // Process...
   }
}

First, the instanceof is always false and if I try to cast the value it goes the exception above.

Possible if the two class instances came from different class loaders. Possible in Java EE environments. – ernest_k Jan 02 '19 at 16:03
@NicholasK Obviously, but the point is that it should enter the `IF` clause. – Joe Almore Jan 02 '19 at 16:04
Can you perhaps describe your runtime? – ernest_k Jan 02 '19 at 16:05
@ernest_k I am not using Java-EE but Apache-Felix – Joe Almore Jan 02 '19 at 16:06
