ERROR Attempted to append to closed appender

[mcweba]

The request logging feature seems to have a bug when a special combination of filter values (url, method, destination) are configured in the logging resource.

The following configuration defines a filter for an url and the destination where to log the requests. This configuration works without any problems:

{
  "headers": [],
  "payload": {
    "destinations": [
      {
        "name": "requestLog",
        "type": "file",
        "file": "requestsTest.log"
      }
    ],
    "filters": [
      {
        "url": "/playground/server/tests/exp/.*",
        "destination": "requestLog"
      }
    ]
  }
}

The following configuration also works without problems. This configuration again defines an url and the method (PUT) to log. The destination is configured with the system property org.swisspush.logging.dir:

{
  "headers": [],
  "payload": {
    "destinations": [
      {
        "name": "requestLog",
        "type": "file",
        "file": "requestsTest.log"
      }
    ],
    "filters": [
      {
        "url": "/playground/server/tests/exp/.*",
        "method": "PUT"
      }
    ]
  }
}

Not working configuration

When using all three filter values (url, method and destination), the requests are not written to the logfile and the following error occurs:

log4j:ERROR Attempted to append to closed appender named [requestLog].

An example of such a logging resource would be:

{
  "headers": [],
  "payload": {
    "destinations": [
      {
        "name": "requestLog",
        "type": "file",
        "file": "requestsTest.log"
      }
    ],
    "filters": [
      {
        "url": "/playground/server/tests/exp/.*",
        "method": "PUT",
        "destination": "requestLog"
      }
    ]
  }
}
