In the Eclipse SDK 4.32 RC2, on Ctrl+hover I see Open Call Hierarchy for a record (TestRecord) and for an enum (TestEnum) as expected, but not for a class (TestClass):

public class OpenCallHierarchyTest {

	public class TestClass { }

	public record TestRecord(int x) { }

	public enum TestEnum { VAL }

	public interface TestInterface { }

}

Strange ... I just checked with https://download.eclipse.org/eclipse/downloads/drops4/S-4.32RC2a-202406010610/ and it works as expected.

(EDIT: works with only other RC1 build as well :https://download.eclipse.org/eclipse/downloads/drops4/S-4.32RC2-202405291800/ )

Thanks for checking. You are right, the menu item Open Call Hierarchy is there, but hidden by the horizontal scrollbar on Windows 11 with a high-DPI display (3840 x 2400; scaling: 250%):

For the record, the enum and the interface the Ctrl hover menu has only two menu items without scrollbars as expected.
