Review Comment:
Same noted below! :-D
> Adapter when locking should "give up and retry"
> -----------------------------------------------
>
> Key: MRESOLVER-349
> URL: https://issues.apache.org/jira/browse/MRESOLVER-349
> Project: Maven Resolver
> Issue Type: Task
> Components: Resolver
> Affects Versions: 1.9.7
> Reporter: Tamas Cservenak
> Assignee: Tamas Cservenak
> Priority: Major
> Fix For: 1.9.8
>
>
> Somewhat in relation to MRESOLVER-346, but sync context (the named lock
> adapter to be more specific) instead of holding as many it could locked so
> far (and cause lock timeouts), should simply give up all and retry.
