@TomasVotruba it seems cause error on downgrade process

[TomasVotruba]

I see 👍

[TomasVotruba]

I'm exploring it and there is infinite loop.
When I exclude the DowngradeJsonDecodeNullAssociativeArgRector the downgrade continues well.

The file it fail on is: vendor/clue/ndjson-react/src/Decoder.php

bin/rector p vendor/clue/ndjson-react/src/Decoder.php -c build/config/config-downgrade.php -n --clear-cache --debug

I tried rollback config/phpstan/parser.neon locally and it works again for this by this PR #1789

# see original config.neon in phpstan.neon - https://github.com/phpstan/phpstan-src/blob/386eb913abb6ac05886c5642fd48b5d99db66a20/conf/config.neon#L1582

That only hides the bug. There is infinite loop with if condition.

This is the reproducer:

vendor/bin/phpunit rules-tests/DowngradePhp72/Rector/FuncCall/DowngradeJsonDecodeNullAssociativeArgRector/DowngradeJsonDecodeNullAssociativeArgRectorTest.php --filter test#3

I can't reproduce it:

 vendor/bin/phpunit rules-tests/DowngradePhp72/Rector/FuncCall/DowngradeJsonDecodeNullAssociativeArgRector/DowngradeJsonDecodeNullAssociativeArgRectorTest.php --filter test#3
PHPUnit 9.5.13 by Sebastian Bergmann and contributors.

OK (1 test, 2 assertions)

and for already transformed, there is already test for it:
