- == New features
-
- AspectJ 1.9.22 supports https://openjdk.java.net/projects/jdk/22/[Java 22], its final and preview features, such as:
-
- * JEP 456: Unnamed Variables & Patterns
- * JEP 459: String Templates (Second Preview)
- * JEP 463: Implicitly Declared Classes and Instance Main Methods (Second Preview)
- * JEP 447: Statements before super(...) (Preview)
-
- The following Java 22 features are API or JVM only, therefore irrelevant for the compiler and should just work
- out of the box:
-
- * JEP 423: Region Pinning for G1
- * JEP 454: Foreign Function & Memory API
- * JEP 458: Launch Multi-File Source-Code Programs
- * JEP 462: Structured Concurrency (Second Preview)
- * JEP 464: Scoped Values (Second Preview)
- * JEP 457: Class-File API (Preview)
- * JEP 461: Stream Gatherers (Preview)
- * JEP 460: Vector API (Seventh Incubator)

- [[ajc_build_system_requirements]]
- === AspectJ compiler build system requirements
-
- Since 1.9.21, the AspectJ compiler `ajc` (contained in the `aspectjtools` library) no longer works on JDKs 11 to 16. The
- minimum compile-time requirement is now JDK 17 due to upstream changes in the Eclipse Java Compiler (subset of JDT
- Core), which AspectJ is a fork of. You can still compile to legacy target versions as low as Java 1.3 when compiling
- plain Java code or using plain Java ITD constructs which do not require the AspectJ runtime `aspectjrt`, but the
- compiler itself needs JDK 17+. Just like in previous AspectJ versions, both the runtime `aspectjrt` and the load-time
- weaver `aspectjweaver` still only require JRE 8+.
-
- History: Since 1.9.8, the AspectJ compiler ajc needed JDK 11+, before then JDK 8+.
-
- [[ltw_java_16]]
- === Use LTW on Java 16+
-
- **Since AspectJ 1.9.21.1, using `--add-opens` is no longer necessary!** The additional JVM command-line option was
- necessary for LTW on JRE 16+ in all AspectJ versions up to 1.9.21. Since AspectJ 1.9.21.1, the LTW agent uses an
- alternative approach for defining new classes during weaving, which works without `--add-opens` - at least for now, i.e.
- JDKs 8 to 22. There still is no canonical solution, because link:https://bugs.openjdk.org/browse/JDK-8200559[JDK-8200559]
- is still unresolved since 2018.
-
- [[compile_with_preview]]
- === Compile with Java preview features
-
- For features marked as preview on a given JDK, you need to compile with `ajc --enable-preview` and run with
- `java --enable-preview` on that JDK.
-
- Please note, that you cannot run code compiled with preview features on any other JDK than the one used for compilation.
- For example, records compiled with preview on JDK 15 cannot be used on JDK 16 without recompilation. This is a JVM
- limitation unrelated to AspectJ. Also, e.g. sealed classes are preview-1 on JDK 15 and preview-2 on JDK 16. You still
- need to recompile, no matter what.
