angryjet fails starting with go 1.22

What happened?

Following the official guidelines to create a custom provider, all the steps can be run until go generate.

then, go generate panics with a backtrace

Error: Process completed with exit code 2.

How can we reproduce it?

The problem can be easily reproduced on github action workers.

Here is a workflow reproducing the problem:

name: Go

on:
  push:
    branches: [ "*" ]
  pull_request:
    branches: [ "*" ]

jobs:

  build:
    continue-on-error: true
    strategy:
        fail-fast: false
        matrix:
          version: [20, 21, 22]

    runs-on: ubuntu-latest
    steps:

    - name: Set up Go
      uses: actions/setup-go@v4
      with:
        go-version: '1.${{ matrix.version }}'
    - name: Install CLI
      run: go install github.com/crossplane/crossplane-tools/cmd/angryjet@master

    - name: Build
      run: |
        git clone https://github.com/crossplane/provider-template.git
        cd provider-template
        make submodules
        export provider_name=MyProvider
        make provider.prepare provider=${provider_name}
        export group=sample
        export type=MyType
        make provider.addtype provider=${provider_name} group=${group} kind=${type}
    - name: generate
      run: |
        cd provider-template
        make generate
    - name: go run angryjet
      if: always()
      run: |
        cd provider-template
        (
          cd apis
          go run -tags generate github.com/crossplane/crossplane-tools/cmd/angryjet generate-methodsets --header-file=../hack/boilerplate.go.txt ./...
        )
    - name: call angryjet
      if: always()
      run: |
        cd provider-template
        (
          cd apis
          angryjet generate-methodsets --header-file=../hack/boilerplate.go.txt ./...
        )

As we can see in this run, the build works well for go 1.20 and 1.21.

It though fails on go 1.22 regardless the way the angryjet command is called (make generate, go run or locally build command)

What environment did it happen in?

Crossplane version: Not required

I could reproduce the error locally as well as in github actions using ubuntu-latest

[tjamet]

Digging slightly in this issue, the problem seems to be related to loading the packages and its loading mode.
Indeed, extracting packages.Load in a dedicated module, we can reproduce the problem, when running towards this repository.
However removing both flags packages.NeedSyntax | packages.NeedDeps, the extracted command succeeds

package main

import (
	"fmt"

	"golang.org/x/tools/go/packages"
)

func testLoadModule(message string, mode packages.LoadMode) {
	defer func() {
		if r := recover(); r != nil {
			fmt.Println(message, "panicked")
		}
	}()
	_, err := packages.Load(&packages.Config{Mode: mode}, "./...")
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(message, "OK")
	}
}

func main() {
	testLoadModule("packages.NeedName | packages.NeedFiles | packages.NeedImports | packages.NeedTypes", packages.NeedName|packages.NeedFiles|packages.NeedImports|packages.NeedTypes)
	testLoadModule("packages.NeedName | packages.NeedFiles | packages.NeedImports | packages.NeedTypes | packages.NeedSyntax | packages.NeedDeps", packages.NeedName|packages.NeedFiles|packages.NeedImports|packages.NeedTypes|packages.NeedSyntax|packages.NeedDeps)
}
