Commit c73cd3764676e4234ef0d00339cea45afe0df754 in aries-rsa's branch
refs/heads/master from Arnoud Glimmerveen
[ https://gitbox.apache.org/repos/asf?p=aries-rsa.git;h=c73cd37 ]
Two inconsistency introduced with ARIES-1941: (#34)
1) The copy of the keySet was incorrectly removed by 927d0b3, and is needed
regardless of the external methods being thread-safe.
2) Clear method of MultiMap must use the same mutex as the other public methods.
> Thread unsafe iteration of thread-safe MultiMap by TopologyManagerImport

> The TopologyMangerImport class uses the MultiMap (Map<String, Set<T>>). The
> operations on the MultiMap itself are thread safe (by means of synchronised
> keyword), however in some cases the Set<T> value is obtained and iterated
> over, without holding the right mutex. As a result you may see
> ConcurrentModificationExceptions.
