This PR resolves a critical compilation issue that was preventing the project from building on Java 17 environments.

Problem

The project was encountering a Java compiler internal error when building:

java.lang.NullPointerException: Cannot read field "bindingsWhenTrue" because "currentBindings" is null
	at jdk.compiler/com.sun.tools.javac.comp.Attr.handleSwitch(Attr.java:1795)

This error was caused by an incompatibility between:

  • Lombok version 1.18.20
  • Java 17 compiler
  • Maven compiler plugin 3.8.1

The issue manifested during annotation processing when Lombok generated code containing switch statements that triggered a bug in the Java 17 compiler.

Solution

  • Upgraded Lombok from 1.18.20 to 1.18.24 (includes Java 17 compatibility fixes)
  • Updated Maven compiler plugin from 3.8.1 to 3.11.0 (better Java 17 support)
  • Improved compiler configuration by using release=8 instead of source/target=1.8
  • Added explicit annotation processor paths for better Lombok integration

Verification

  • ✅ API module now compiles successfully
  • ✅ All existing tests pass
  • ✅ Added CompilationTest to verify Lombok annotations and enum usage work correctly
  • ✅ No regressions in existing functionality

Impact

This fix enables developers to build the project on modern Java environments while maintaining Java 8 bytecode compatibility for AEM deployment.

Fixes #193.
