             Summary: Load in-process FnHarness instances with a restricted 
classpath
                 Key: BEAM-4384
                 URL: https://issues.apache.org/jira/browse/BEAM-4384
             Project: Beam
          Issue Type: Improvement
          Components: runner-direct
            Reporter: Thomas Groh


The new classpath can contain the Java harness code and the user's classpath. 
This simulates the SDK container, and removes the need for users to provide 
beam-sdks-java-harness as a dependency.

The idea would be that beam-sdks-java-harness would be a jar containing all of 
its dependencies shaded away similar to what we do for Dataflow. We would embed 
the beam-sdks-java-harness.jar as a jar inside the direct runner jar so we 
wouldn't need to fetch it from Maven and also would be able to solve the 
problem where tests would run from the provided jar.
