HTTP client sends empty messages when FINE log level is enabled
---------------------------------------------------------------
Key: CXF-3466
URL: https://issues.apache.org/jira/browse/CXF-3466
Project: CXF
Issue Type: Bug
Components: Transports
Affects Versions: 2.4
Reporter: Alessio Soldano
I'm testing JBossWS-CXF integration with Apache CXF 2.4.0 and I'm seeing a
weird behaviour in HTTPConduit.
Basically, when the org.apache.cxf log category is set to DEBUG (I'm using
log4j logging, that's FINE level) I see empty(*) messages being sent from
client to server. Setting the log level to INFO, remove the problem. So I
looked for "isLoggable(Level.FINE" strings in the CXF sources and tried
commenting out them one by one to identify the culprit. Finally isolated it in
the following code in HTTPConduit::onFirstWrite()
if (LOG.isLoggable(Level.FINE)) {
LOG.fine("Sending "
+ connection.getRequestMethod()
+ " Message with Headers to "
+ connection.getURL()
+ " Conduit :"
+ conduitName
+ "\nContent-Type: " + connection.getContentType() + "\n");
}
My guess is one of the calls to the connection in there compromise its state.
(*) actually, capturing the network traffic reveals the http headers only are
written, the body is completely missing
