Eric Milles updated GROOVY-6450:
--------------------------------
Fix Version/s: (was: 4.x)
> String.minus(String) and String.minus(Pattern) are inconsistent with
> List.minus(Collection).
> --------------------------------------------------------------------------------------------
>
> Key: GROOVY-6450
> URL: https://issues.apache.org/jira/browse/GROOVY-6450
> Project: Groovy
> Issue Type: Bug
> Components: groovy-jdk
> Affects Versions: 1.8.9, 2.0.8, 2.1.9, 2.2.0
> Environment: Any
> Reporter: James P. White
> Priority: Major
> Attachments: TestGROOVY_6450.groovy
>
>
> The String.minus operations only remove the first occurrence of the equal
> elements while List.minus removes all occurrences. This is terribly
> inconsistent, as shown in these examples:
> {code}
> $ groovy -e "println ('abcabcabc' - 'b')"
> acabcabc
> $ groovy -e "println ((('abcabcabc' as List) - ('b' as List)).join())"
> acacac
> {code}
> Given my experience with trying work with multisets, I think I prefer the
> remove first/only one semantics. Given String.minus' troubled history it is
> probably less disruptive to change it yet again.
