TYPO3 Core

I have a composer based TYPO3 installation with two extensions: EXT:one and EXT:two.

The extension EXT:one depends on EXT:two. The dependency is defined in the ext_emconf.php.

In the ext_localconf.php of EXT:one I am calling helper-functions / static methods from EXT:two. This throws an error, saying the methods are unknown / not registered, meaning EXT:two is not present / was not loaded when the code in the ext_localconf.php is executed.

In the loading order of the individual ext_localconf.php the alphabetic order of the extensions-folders seems to play a role. No error is thrown, if I rename EXT:one to EXT:zork. "Z" seems to be loaded AFTER "T".

I can fix this issue by adding the dependency to the composer.json of EXT:one:

{
  ...
  "require": {
    "nng/two":"..." 
  }
}

It seems that everything worked fine up till version 11.5
