Support for boundary events on Tasks in jBPM5

Issue

• I have created the process which has a Timer on a Task node. No error with Designer but I'm getting the following errors at runtime.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kbase': Invocation of init method failed; nested exception is java.lang.RuntimeException: [-1,-1]: Process 'xxxx' [defaultPackage.xxxx]: Timer node 'Repeatable Timer' [6] has no incoming connection.
