Subject [jira] Created: (DERBY-3539) Add possibility to inject errors in replication message layer

Add possibility to inject errors in replication message layer

                 Key: DERBY-3539
                 URL: https://issues.apache.org/jira/browse/DERBY-3539
             Project: Derby
          Issue Type: Improvement
          Components: Replication
    Affects Versions:
            Reporter: Jørgen Løland
            Priority: Minor

Some replication functionality is difficult to test automatically, e.g. because human intervention
is required. Examples of things that are difficult to test:

* behavior when the replication log buffer is nearly full
* network connection is lost without resulting in an exception (e.g., a network cable is unplugged,
a switch dies etc)

These scenarios would be easier to test automatically if we could inject errors like randomly
loosing log chunks, don't answer ping calls, not send log chunks for 1 minute etc.

Replication issues that need failure injection should link to this issue.
