Dynamic toolbar won't appear in Eclipse RCP app

Question

I built an RCP app with java 17 and Eclipse 2024.06 using Maven Tycho plugin 4.0.8.

In plugin.xml I defined a toolbar.

<plugin>
    <extension point="org.eclipse.ui.menus">
        <menuContribution locationURI="toolbar:org.eclipse.ui.main.toolbar?after=additions">
            <toolbar id="com.company.project.ui.admin.zone.toolbar">
                <dynamic
                        class="com.company.project.ui.admin.zone.editor.util.SelectZonesDropDownContributionItem"
                        id="com.company.project.ui.admin.zone_selector_contribution">
                    <visibleWhen checkEnabled="false">
                        <with variable="activeEditorId">
                            <equals value="com.company.project.client.editors.zone"></equals>
                        </with>
                    </visibleWhen>
                </dynamic>
            </toolbar>
        </menuContribution>
    </extension>
</plugin>

I expect the toolbar to be appeared in my app but nothing happens, there is just empty space on the toolbar where my dropdowns should be located. In the past, the application had been built with Eclipse Mars (using Eclipse Product export wizard) and Java 8 and it worked. Recently I updated the Eclipse framework and started to use Tycho to build the app. Please let me know if any information needed to understand the problem better.

UPD: The reproducible example might be found here here

UPD2: The exception I get when toolbar is created:
