Diagnostic Steps
Check if the application is an upgraded version from JIRA 6.x or earlier and there's a modified
jpm.xml.(located in the <jira-application-dir>/WEB-INF/classes subdirectory of theJIRA Installation Directory.1 2 3___ Modifications ___________________________ Modified Files : jira-application.properties, jpm.xmlIn
jpm.xml, <key>jira.thumbnails.scaling.factor</key> is not found.
Cause
The jpm.xml file, which is placed at $JIRA_INSTALL/atlassian-jira/WEB-INF/classes folder, has been modified. This can be diagnosed upon checking the startup log entries on atlassian-jira.log or catalina.out.
<key>jira.thumbnails.scaling.factor</key> does not exist in jpm.xml in earlier version of JIRA, if the jpm.xml from earlier version of JIRA is used in JIRA 7.x, there will be problem rendering the attachmentmodule and attaching new files.
Solution
Workaround
Add the property below to the
jpm.xmland restart JIRA.1 2 3 4 5 6 7 8<property> <key>jira.thumbnails.scaling.factor</key> <default-value>4</default-value> <type>uint</type> <admin-editable>false</admin-editable> <sysadmin-editable>true</sysadmin-editable> <requires-restart>false</requires-restart> </property>
Resolution
Replace the modified jpm.xml with the original file corresponding to the JIRA version.
If
jpm.xml
must be modified, it's advised to use the original
jpm.xml
and add in other properties instead of copying it from the source version. This is because
any values that you customize in it will not be migrated automatically during subsequent JIRA upgrades.
