Resolution: Unresolved

Major
I've face the NPE error (stacktrace below). The last things I did before this error happened after restart were
- Run a multibranch pipeline job which has locked on waiting 'maven' node
- Configure Maven tool to auto-label nodes with 'Maven maven Mvn mvn Java java' labels
- Restart
For now after restart I get this stacktrace on every screen, looks like the system tries to run the job and fails

[JENKINS-43959] NPE with Tool Labels Plugin
As a workaround I have to remove the 'tool-labels-plugin', at least I am now able to start the jenkins
I have created a component for this plugin.
From what I see its codebase has not been migrated to GitHub. Asked in IRC if we still have it somewhere. Otherwise we may have to depublish the plugin, CC danielbeck
I see the same null pointer exception problem. I've removed the tool-labels-plugin from my environment and confirmed that resolves the issue.
I updated a few plugins (cmakebuilder, git parameter, metrics, and xunit) and now see the fatal stack trace at startup:

That fatal stack trace was resolved when I removed the tool-labels-plugin from my installation. At initial startup after the plugin removal, an administrative monitor appeared which warned that the cmakebuilder tool had a tool-labels-plugin reference which could not be resolved. I assume that was the root of my problem. The NPE was preceded by my use of a job which auto-installed a cmake version using cmake as a tool. I suspect some interaction between the two was the cause of the fatal exception in my installation.
It appears that kazssym was maintaining the plugin from a Bitbucket repository. There is a null pointer exception issue reported there. Last commit that I see on that Bitbucket repository was 2 years ago.
Btw the Issue Tracker link from the plugin page leads to invalid search query as the 'tool-labels-plugin' component does not exist. I was also unable to link proper plugin to component
