public class ModuleProjectRenameParticipant extends RenameParticipant
The rename participant of an IIZI Module project: a project is renamed on a quiet, saved workspace (the owner's ruling of 2026-10-14 00:35, CC-FIX-IIZIGO-G4-PROJECT-LIFECYCLE). It changes nothing in the rename itself; its conditions make sure that nothing of the project waits to be written after the rename's operation:
  1. No editor of a file of the project holds unsaved changes, or the rename is refused with a message naming them. The Refactor > Rename of a Java project saves every modified editor before its wizard opens (JDT's RenameJavaProjectProcessor.getSaveMode() is SAVE_ALL, applied by JDT's RefactoringSaveHelper, which asks unless "always save" is set), so the refusal is what the other paths meet: LTK's resource rename, and a rename run by code.
  2. The project's preferences and its IIZI Module settings are written now when they hold unsaved changes: a pending "Save Module project settings" job would write the settings into the project of the old name after the rename.
  3. IIZI's jobs of the project (the jobs whose family is the project) are waited for, never on the UI thread, under the refactoring's progress monitor, which can cancel the wait. The refactoring wizard checks the conditions under the workspace root rule, which it acquires under its progress dialog, so builds, refreshes and every other job holding a rule have ended before this check runs. A job of the project that cannot run while the rename holds its rule, or one still running when the wait ends, refuses the rename with a message naming it.
