> The method getDependents(Provider) in BasicDependencyManager isn't using
> proper synchronization in cases where a list has to be compiled by combining
> in-memory and on-disk dependencies. Returning a reference to the list
> obtained from the shared map is also a bug.
> The test lang.XplainStatisticsTest.testSimpleQueryMultiWithInvalidation
> failed due to this issue (see [1]).
