Can't bind a class to a custom node.

When binding the class to a custom node the "Available blocks" doesn't show any classes which were created.

@raditha Can you attach zip of your project?

[raditha]

@dpavlikovskiy Sure.I am using JDK 1.7 with neuro4j studio 0.9.The project is attached.
jwtTest3.zip

[dpavlikovskiy]

@raditha please download latest (2.0.1) studio from http://static.neuro4j.org/download/studio/ (0.9 is very old version). Also it requires java8... Let me know if it solves your problem

@dpavlikovskiy Downloading the latest and upgrading to java 1.8 solved the issue. But when i'm trying to run the example provided in the documentation the following exception occurs.

@raditha What example did you try? WorkflowExample from https://github.com/eternita/workflow/tree/master/tutorials/

[raditha]

@dpavlikovskiy I tried the workflowExample from the tutorials.

[dpavlikovskiy]

@raditha I have updated version to 3.4.1 in tutorials
