[aspectj-users] Support for @Repeatable annotations

[Johan Fabry <jfabry@xxxxxxxxxxxxx>]

Hi all,

apologies if this is a FAQ, my mailing list searches did not turn up any matches.

I’m experimenting with the @Repeatable annotations of Java 8 on some aspects, and apparently AspectJ does not provide any support for @Repeatable, as I get an exception at some point. (Below are the details of my setup and the offending annotation description.) 

Am I correct that there is no support? Are there any plans to include it?

Thanks in advance!


AspectJ Compiler version: 1.8.3.20140820082000	

Relevant stack trace (cutting out a ton of frames at the bottom as I’m doing the experiments in Clojure):
