The minimum compile-time requirement is now JDK 11 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 + <tt>aspectjrt</tt>, but the compiler itself needs JDK 11+.

Therefore, you need to set the JVM parameter <tt>--add-opens java.base/java.lang=ALL-UNNAMED</tt> in + order to enable aspect weaving. This is due to the fact that the weaver uses internal APIs for which we have not found + an adequate replacement yet when defining classes in different classloaders. +</p> + +<h3>Compile with Java preview features</h3> + +<p> + For features marked as preview on a given JDK, you need to compile with <tt>ajc --enable-preview</tt> and run with + <tt>java --enable-preview</tt> on that JDK. +</p> +<p> + 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. +</p> + +<hr> + +<p> + <b>Available:</b> 1.9.9 available DD-MMM-2022 +</p> + +</body> + +</html> |
