Cause
This exception has been observed after upgrading a Jira instance that was running behind a reverse proxy to the 9.0.x version.
After looking at the JAVA input arguments in the setenv.sh file, we noticed the following line:
1
JVM_SUPPORT_RECOMMENDED_ARGS="'-Dhttp.proxyHost=XX.X.X.XX -Dhttp.proxyPort=3128 -Dhttps.proxyHost=XX.X.X.XX -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts=*.xyz.org'"Because of the apostrophe within the arguments in the setenv.sh file, the http.proxyHost property considered all the entries as a unique value as shown in the atlassian-jira.log.
1
http.proxyHost : XX.X.X.XX -Dhttp.proxyPort=3128 -Dhttps.proxyHost=XX.X.X.XX -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts=*.xyz.orgSolution
1. Stop Jira;
2. Edit the system properties and remove the apostrophe from the JVM_SUPPORT_RECOMMENDED_ARGS in the setenv.sh file as below:
1
JVM_SUPPORT_RECOMMENDED_ARGS="-Dhttp.proxyHost=XX.X.X.XX -Dhttp.proxyPort=3128 -Dhttps.proxyHost=XX.X.X.XX -Dhttps.proxyPort=3128 -Dhttp.nonProxyHosts=*.xyz.org"3. Also ensure that there are no typos or blank spaces on each property=value;
4. Start Jira;
5. Test the application links.
