jbpm gateway loop problem

[chobk]

I'm currently testing a jbpm 6.4

I tried to implement iteration through the gateway.

Attach an error occurred when it was tested as a source.

I would like to know whether a gate way is wrong with the configuration you want to limit the loop processing.

Error information as follows:

Exception in thread "main" java.lang.StackOverflowError
