Description

The FileDataStore can throw a NPE when doing garbage collection, if there is file I/O problem (for example an access rights problem). The reason is that it doesn't check if File.list / listFiles returns null. Stack trace:

Exception in thread "Thread-461" java.lang.NullPointerException
