Hello,
we have JIRA Software 7.3.3 with JIRA Core 7.3.3 and whenever someone try to EDIT issue from issue filter (Issue search) its freeze, but whenever you open only the one issue you can edit it without problem. In Log Analyzer there are these errors.
NullPointerException when Authenticating from IE
Getting "Unknown error loading feed from" when subscribe Fisheye Gadget in JIRA
In the log there are lots of errors with illegal characters like this.
Caused by: java.net.URISyntaxException: Illegal character in path at index 34: /secure/attachment/95131/...
Do you think it could be something in common with the problem?
