NNStorage does not synchronize iteration on a synchronized list #64

emopers · 2015-12-30T09:46:28Z

In line 839 of NNStroage.java#reportErrorsOnDirectories, the synchronized list, sds
is iterated in an unsynchronized manner, but according to Oracle Java 7 API specification,
this is not thread-safe and can lead to non-deterministic behavior.
This pull request adds a fix by synchronizing the iteration on sds. The synchronized list is passed to method reportErrorsOnDirectories from here

…pecification
