Why do you think it is JMeter bug? I'm inclined that it is jmeter-plugins-manager bug. What it does it requests CheckBox.icon from UIDefaults, however, the icon is not there. Note: there's no specification that requires the value to be there. https://github.com/undera/jmeter-plugins-manager/blob/d801d8b8d8b7e7d31c8d55203f95b1702b93ec69/src/main/java/org/jmeterplugins/repository/CheckBoxList.java#L31 So jmeter-plugins-manager should add a null check (or remove the use of CheckBox.icon completely). I've filed https://github.com/weisJ/darklaf/issues/125 so Darklaf could consider adding CheckBox.icon property.

I suggest we reopen until it is fixed in LAF or JPM.
Is there something to be done at JMeter side? Who's working in JPM fix? Why the release of JMeter gets blocked by JPM?
(In reply to Vladimir Sitnikov from comment #3) > Is there something to be done at JMeter side? > Who's working in JPM fix? > I'll propose a fix if needed. > Why the release of JMeter gets blocked by JPM? JPM is now an important tool for installing plugins. If a change in JMeter breaks it, then at least we should report it, if possible fix JPM.
This has been fixed in JPM through this PR: - https://github.com/undera/jmeter-plugins-manager/pull/53 And released in 1.4
This issue has been migrated to GitHub: https://github.com/apache/jmeter/issues/5278
