Mathias Krueger updated NIFI-15686:
-----------------------------------
Description:
If a user adds a ListenSyslog processor to the canvas and doesnt configure a
port, accessing nifi-api/flow/listen-ports results in the message:
An unexpected error has occurred. Please check the logs for additional details.
in nifi-user.log the following NPE is thrown
{code:java}
java.lang.NullPointerException: Cannot invoke "java.lang.Integer.intValue()"
because "tcpPortNumber" is null
at
org.apache.nifi.processors.standard.ListenSyslog.getListenPorts(ListenSyslog.java:357)
{code}
In ListenSyslog in method getListenPorts should a null value check for TCP and
UDP port be added.
Also if the users enters an invalid value (e.g. empty text) this method should
not fail.
This problem exists for every components that inherits the method
getListenPorts() form the interface ListenComponent
