Lukas Wulff commented on LANG-1668:
-----------------------------------
I worked this out by comparing the two versions on GitHub:
3.11:
[https://github.com/apache/commons-lang/blob/rel/commons-lang-3.11/src/main/java/org/apache/commons/lang3/reflect/MethodUtils.java]
3.12:
[https://github.com/apache/commons-lang/blob/rel/commons-lang-3.12.0/src/main/java/org/apache/commons/lang3/reflect/MethodUtils.java]
> Unlisted breaking change in behaviour of MethodUtils#getMatchingMethod
> ----------------------------------------------------------------------
>
> Key: LANG-1668
> URL: https://issues.apache.org/jira/browse/LANG-1668
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.reflect.*
> Affects Versions: 3.12.0
> Reporter: Lukas Wulff
> Priority: Critical
> Labels: newbie
>
> After upgrading from 3.11 to 3.12 some Unit Tests of mine were failing.
> I tracked this back to an undocumented change in lang3:
> MethodUtils#getMatchingMethod is behaving differently.
> Previously, it returned the closest match when no exact match could be found.
> Now, it throws an IllegalStateException when there is no unique result.
> It would have saved me some time if this had been noted in the change notes.
> Not quite sure where to bring this up or whether this qualifies as a bug, but
> I hope I'm helping by mentioning it here.
