Rainer Reich commented on MRESOLVER-123:
----------------------------------------

I did some tests with {{-Daether.checksums.algorithms=SHA-1}} and without 
takari and executed a lot of builds without any problems. (y)
Are you still interested in a log of a successful run?

We would definitely be very happy to see this fix in the next Maven version.

Regarding Nexus compatibility, I don't know if we find out where the wrong 
checksums came from but we might not be the only ones with problems like these, 
so I hope the checksum option is going to get documented and officially 
supported.

> This is an umbrella ticket for a long standing issue with Maven Resolver: Our 
> concurrency support is mediocre in a way that if two or more threads try to 
> download the same file and fail to queue those write actions nicely. The 
> problem is that The {{SyncContext}} and the its factory provided by Maven 
> Resolver does not employ any locking at all. As layed out in detail in 
> MRESOLVER-114 we need striped read write locks on artifacts and its metadata. 
> This issue shall track progress on it. Even Takari Concurrent Repository 
> extension does not help because it is only intended to synchronize concurrent 
> access by multple JVMs and not threads.
