-------------------------------------------------------------------
To keep you informed, here is what has been done regarding how the compiler
generate the method:
* I used {*}{{expect}}{*}, for the first time. This tool allow script
automation. I attached the script, the syntax is not complex and things can get
improved iteratively.
* Then, I traced all methods via {{jdb}} AFTER reaching
{{AsmClassGenerator.visitStdMethod}} (see expect file)
Then, I indent the output of the previous commands, with a Groovy script.
The output file is huge, even for simple class code. So, I use grep / awk to
format around expected symbols..
This process is arch and "brute force", but I am a little blind on what I am
supposed to find. Nevertheless, it is fun in some ways.. Hope to find my error
soon.

> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 3.0.21
> Environment: $ java -fullversion
> openjdk full version "17.0.10+7"

> at
> org.codehaus.groovy.classgen.asm.StatementWriter.writeReturn(StatementWriter.java:615)
> [. . .]
> Tell me if you need a more complete stacktrace. I try to work around this
> bug, changing the AST, without success. The error looks the same {*}each
> time{*}.
> To reproduce:
> $ tar xvfz testcase-asttransform-ko.tar.gz
> $ cd groovyInfra
> $ ./gradlew publishMavenPublicationToMavenLocal
> $ cd ..
> $ cd t620g
> $ ./gradlew assemble
> => BROKEN HERE
> Thanks for your help !
