Symptoms

Setting up a ViewController Project for an Oracle Identity Manager (OIM) custom workflow development according to below document (*1). After adding "OIM View Shared Library" and "OIM Model Shared Library" to the ViewController Project, JDeveloper throws the following "Invalid project format" error into its "Log" window;

(*1) Developing and Customizing Applications for Oracle Identity Governance 12.2.1.4
- 17 Customizing the Interface
-- 17.7 Developing Managed Beans and Task Flows
--- 17.7.2 Setting Up the ViewController Project

Changes

The error occurs in the steps below;
1. Run JDeveloper 12.2.1.4.
2. Display Log windows from tool menu, "Window" > "Log".
3. Create a new Application, select "ADF Fusion Web Application", and then click "OK".
4. Click "Next" in all steps to create the Application, and then click "Finish".
5. Right-click the "ViewController" project, and select "Project Properties".
6. Select "Libraries and Classpath".
7. Click "Add Library", click "Load Dir", select IDM_HOME/server/jdev.lib, add "OIM View Shared Library" and "OIM Model Shared Library", and click "OK".
-> The "Invalid project format" error appears in the Log window.

NOTE: It's outside of this document scenario, but the error occurs in standalone JDeveloper 12.2.1.4 also without OIM installation by loading the oracle-page-templates-ext.jar file directly instead of the OIM libraries;
"Libraries and Classpath" -> "Add JAR/Directory..." -> Open <FMW_HOME>/jdeveloper/adfv/jlib/oracle-page-templates-ext.jar

The issue does not occur in JDeveloper and OIM 12.2.1.3.
