Building a Stream

Changed the logicClass.getContructor(...) to logicClass.getConstructors()(0) to find the correct constructor but it is still not possible to instantiate a stage object due to a ArgumentMissMatchException.

But the found constructor's parameterTypes are as expected except the Shape missing the Dataset Type.

Using Scala reflection instead of the java librarys might be a solution

Hey Folks,
thanks @EndallBatan93 for raising this issue and thanks @Avoliq for clarification.
I found the problem in the FilterManager. The method loadStageLogicClass loads the StageLogic class but to do this, it creates a new ClassLoader. That leads to the ArgumentMissMatchException later, because two classes (the parameter types of the constructor) are only equal if both where loaded with the same ClassLoader.

For a first fix i replaced:

ScalaClassLoader(getClass.getClassLoader).tryToLoadClass(className)

with:

Option(getClass.getClassLoader.loadClass(className))

Kind regards,
Elmar

Pleas let me know if the problem still exists.
