replace_all with alternation expects multiple matching path, breaks with single matching path

[TobiasNx]

Input:

{
  "describedBy" : {
    "type" : [ "BibliographicDescription" ],
    "dateCreated" : "20220711"
  }
}

FIX:
replace_all("describedBy.dateCreated|dateModified","2","?")

Expected:

{
  "describedBy" : {
    "type" : [ "BibliographicDescription" ],
    "dateCreated" : "?0??0711"
  }
}

Results in Error:

org.metafacture.metafix.FixExecutionException: Error while executing Fix expression (at file:/tmp/metafix5253049504537349638.fix, line 1): replace_all("describedBy.dateCreated|dateModified","2","?")
...
Caused by: java.lang.IllegalStateException: Expected Array or Hash, got String

See in Playground here.

Multiple Path work, see here.

replace_all("describedBy.dateCreated|dateModified","2","?")

Just to be extra clear: Any other potential bugs notwithstanding, I would strongly advise against relying on this wrong behaviour in the current Metafix implementation! See #143.

This also breaks with "flat" alteration.
replace_all("dateCreated|dateModified","2","?")

PS: We went with separate replace_all functions to circumvent this problem.

Good. Then we should focus on that.
