Recieving Several Java Null Pointer Exceptions in JIRA Log

Bryan Trummer - ReleaseTEAM

I am receiving several JAVA NULL POINTER EXCEPTIONS messages in my log. It would appear that it may be for only one project. However, I am having an issue determining what the actual issue is:

2014-12-11 10:28:48,682 http-bio-8443-exec-17 ERROR reer01 628x25793x1 1cj02ju 10.7.7.135 /secure/QuickEditIssue.jspa [atlassian.event.internal.AsynchronousAbleEventDispatcher] There was an exception thrown trying to dispatch event 'com.atlassian.jira.event.issue.IssueEvent@153d79aa[issue=TS0001-447,comment=<null>,worklog=<null>,changelog=[GenericEntity:ChangeGroup][id,106519][author,reer01][created,2014-12-11 10:28:48.51][issue,15050],eventTypeId=2,sendMail=true,params={eventsource=action, baseurl=https://jira.planetgroupinc.com:8443},subtasksUpdated=true]' from the invoker 'SingleParameterMethodListenerInvoker{method=public void com.atlassian.jira.plugins.autolink.IssueEditedListener.issueEdited(com.atlassian.jira.event.issue.IssueEvent), listener=com.atlassian.jira.plugins.autolink.IssueEditedListener@6689b100}'.
java.lang.RuntimeException: java.lang.NullPointerException

I do use scriptRunner but not sure if there is a transition that is causing this or where it is even causing it at. Any ideas? I am running JIRA 6.0.8

Accepted answers

The NPE is happening inside the code of the autolinks plugin, which isn't officially supported:

Set&lt;String&gt; existingKeys = new HashSet&lt;String&gt;();
IssueLinkService.IssueLinkResult issueLinks = issueLinkService.getIssueLinks(issueEvent.getUser(), issueEvent.getIssue());
if (issueLinks.isValid()) {
    LinkCollection linkCollection = issueLinks.getLinkCollection();
    IssueLinkType linkType = issueLinkTypeFactory.getIssueLinkType();
    List&lt;Issue&gt; outwardIssues = linkCollection.getOutwardIssues(linkType.getName());  // &lt;=== NPE is here
    if (outwardIssues != null) {
        existingKeys.addAll(transform(outwardIssues, new Function&lt;Issue, String&gt;() {

Which means either linkCollection or linkType is null. The linkCollection shouldn't be null because issueLinks.isValid() is properly checked, so my suspicion is that issueLinkTypeFactory.getIssueLinkType() returned null. That code does this:

public IssueLinkType getIssueLinkType() {
    return matchToIssueLinkType(LINK_NAME);
}

private IssueLinkType matchToIssueLinkType(String linkName) {
    Collection&lt;IssueLinkType&gt; linkTypes = issueLinkTypeManager.getIssueLinkTypes();
    for (IssueLinkType linkType : linkTypes) {
        if (linkName.equals(linkType.getOutward())) {
            return linkType;
        }
    }
    return null;
}

And returning null is clearly something that it expects to be able to do when the issue has links, but none of them are mentions.

Perhaps @Pawel Bugalski would be interested in fixing this? smile

Nic Brough -Adaptavist-

Hmm, that error looks like the "automatic linking" plugin is failing.

Could you have a look at the configuration for that?

Bryan Trummer - ReleaseTEAM

Thanks for the quick reply. By any chance do you know where that config is located at. I verified that the JIRA AUTOLINK plug in is enabled, however I don't see any config for it minus the normal linking config where you can customize linking to have new links or what not.

Nic Brough -Adaptavist-

Hmm. There may not be any config for it, I thought there was because I've used something similar (you had to enable it by project, which your "it's only happening in one project" made me think of) Try admin -> gg and then type Auto into the search box and see if it returns anything. Also, go to manage plugins, find it, expand the information box and see if it then has a "configure" link there.

Bryan Trummer - ReleaseTEAM

Yeah I thought that as well. It looks like its not only limited to one project. I was wrong when I said that. I did the expand on the information box for the plug in and no configure set up.

Is the stack trace present? If so then even the first few lines of it would likely be helpful. All this really tells us is that the "autolink" plugin hit an NPE while trying to handle an event. There are many reasons why that could happen, but ultimately it is probably a bug in that plugin, even if the bug is just that you can configure it such that this is possible.

Hey Chris, Here is the full stack trace from that error.

The NPE is happening inside the code of the autolinks plugin, which isn't officially supported:

Set&lt;String&gt; existingKeys = new HashSet&lt;String&gt;();
IssueLinkService.IssueLinkResult issueLinks = issueLinkService.getIssueLinks(issueEvent.getUser(), issueEvent.getIssue());
if (issueLinks.isValid()) {
    LinkCollection linkCollection = issueLinks.getLinkCollection();
    IssueLinkType linkType = issueLinkTypeFactory.getIssueLinkType();
    List&lt;Issue&gt; outwardIssues = linkCollection.getOutwardIssues(linkType.getName());  // &lt;=== NPE is here
    if (outwardIssues != null) {
        existingKeys.addAll(transform(outwardIssues, new Function&lt;Issue, String&gt;() {

public IssueLinkType getIssueLinkType() {
    return matchToIssueLinkType(LINK_NAME);
}

private IssueLinkType matchToIssueLinkType(String linkName) {
    Collection&lt;IssueLinkType&gt; linkTypes = issueLinkTypeManager.getIssueLinkTypes();
    for (IssueLinkType linkType : linkTypes) {
        if (linkName.equals(linkType.getOutward())) {
            return linkType;
        }
    }
    return null;
}

And returning null is clearly something that it expects to be able to do when the issue has links, but none of them are mentions.

Perhaps @Pawel Bugalski would be interested in fixing this? smile

The magic of a stack trace! Thats a lot of great information. So this seems like something I have to wait for it to be fixed.

Most likely... Let's see what Bugi has to say, since it's his. He doesn't seem to have an issue tracker set up for the plugin, so I've pinged him directly.

Perfect. I appreciate the help!

As @Chris Fuller explained in his answer there was a bug in AutoLink for JIRA plugin. There is now a new version of this plugin available that contains fix to this issue.

Also the root cause of your problem was that AutoLink plugin was looking for Mention link type and was failing with NPE because it could not find it. You can check what issue link types you have configured by looking into: Administration -> System -> Issue Features -> Issue Linking

AutoLink plugin was expecting to find there link type of outward description "mentions". So your problems could have been caused by removing this link type ("Mention" with outward description "mentions") or changing its outward description.

Fixed version of AutoLink plugin will not throw NPE if it can not find this link type. Also it will try to find link type named "Mention" so now one can change outward and inward descriptions of this issue link type.

I hope that will solve your problem.

AH HA. I apparently changed the mentions outward and inward description. I went ahead and updated it.

@Bryan Trummer with fixed version of AutoLink plugin (1.0.1) this would actually work

Bryan Trummer - ReleaseTEAM

Even better! I will get this installed! Thanks for the help Pawel!
