We have added system properties in the file setenv.sh/setenv.bat . In our case the system properties which are added are the forward proxy parameters . eg:
-Dhttp.proxyHost=xyz -Dhttps.proxyHost=xyz -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts = xyz
Cause
A null number was encountered while getting the proxy configuration from system properties. we are missing the http.proxyPort value
Resolution
We are missing the -Dhttp.proxyPort value , so we will need to add the missing proxy parameter to setenv.sh
