"Exception occurred: java.lang.NullPointerException" when updating the fix version on an issue

[JT]

User is receiving a null pointer exception when changing the fix version on an issue. This exception does not happen on all issues in the project - the exception is sporatic.

I have not been able to find any information on this issue. Can anyone give me any insight?

JIRA 4.3.4 running on Linux

Looks like an issue with the User Picker plugin you are using (Not an Atlassian plugin)

In fact it might already be logged as an issue with them - See

https://studio.plugins.atlassian.com/browse/JUP-5

You'll have to communicate to the plugin vendor to try get them to fix

You need to post a stacktrace at the least.
