ALSB 2.1 - throws HttpOutboundMessageContext.RetrieveHttpResponseWork.run: java.lang.NullPointerException (Doc ID 976326.1)

Last updated on MAY 12, 2023

Applies to:

Oracle Service Bus - Version 2.1 to 2.6.1RP [Release Aqualogic Service Bus]
Information in this document applies to any platform.

Symptoms

ALSB throws a NullPointerException instead of a meaningful Exception.

In com.bea.wli.sb.transports.http.HttpOutboundMessageContext.getResponse(), we didn't check _urlConn==null.
Sometimes, _urlConn can be null if this function is called from the callbacks and the socket is closed.
In this case, you see the NPE being propagated to the client in the $fault variable. 

We need to provide a more meaningful message to the $fault variable, even though the exception details are being logged in the log file.

HttpOutboundMessageContext.RetrieveHttpResponseWork.run:
 java.lang.NullPointerException
