Problem Description

eXtended Services Interface (XSI) requests whose response body is empty or null will lead to HTTP 409 error code and NullPointerException could be seen in the logs.

Background

Note: This field notice was originally posted in the BroadSoft Xchange portal and has been moved over to Cisco.com as-is for historical purposes.

Problem Symptom

XSI requests whose response body is empty or null will lead to HTTP 409 error code and a NullPointerException being reported in the logs. This exception has the potential to affect XSI event channels leading to the channels being torn down, which requires the application to restart the channels.

An example of the exception is:

java.lang.NullPointerException
at java.util.regex.Matcher.getTextLength(Matcher.java:1283)
at java.util.regex.Matcher.reset(Matcher.java:309)
at java.util.regex.Matcher.<init>(Matcher.java:229)
at java.util.regex.Pattern.matcher(Pattern.java:1093)
at com.broadsoft.protocols.oci.util.OCIDataUtility.removePasswords(OCIDataUtility.java:451)
at com.broadsoft.xsi.base.BwXsiUtilities.scrubber(BwXsiUtilities.java:79)

When the XSI event channels are affected by this issue, this exception might be reported:
