title: UnsatisfiedDependencyException Error with bean name Unsatisfied dependency expressed through field
body: <p>I'm a novice using a microservice architecture and want to access a bean from another module which uses camunda (a read only business process tool (library)). The error unsatisfied dependency is coming from a camunda interface  yet I don't require any bean from camunda in my current module so i tried to exclude it with the code below:</p>
  
  <pre><code>@Configuration
  @ComponentScan(basePackages = {"com.example"}, excludeFilters={
   @ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, value=SpringProcessEngineServicesConfiguration.class)}) 
  </code></pre>
  
  <p>The current module won't start giving the stacktrace below:</p>
  
  <pre><code>org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.camunda.bpm.engine.spring.SpringProcessEngineServicesConfiguration': Unsatisfied dependency expressed through field 'processEngine': Error creating bean with name 'processEngineFactoryBean': FactoryBean threw exception on object creation; nested exception is org.camunda.bpm.engine.exception.NotValidException: Filter name must not be null or empty: name is null; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngineFactoryBean': FactoryBean threw exception on object creation; nested exception is org.camunda.bpm.engine.exception.NotValidException: Filter name must not be null or empty: name is null
