From: Alexander Kriegisch Date: Mon, 21 Aug 2023 10:18:27 +0000 (+0700) Subject: Regression test for Spring issue 27761 X-Git-Tag: V1_9_20_1~9 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=e2a355b37935faf9a8de1ce7ca1f134b5a9df891;p=aspectj.git Regression test for Spring issue 27761 Relates to spring-projects/spring-framework#27761. The test needs an ASM-generated class file with reordered methods in order to reproduce the issue in plain AspectJ. The test fails now, but should pass after the fix.
