KeyValueFilter.accept() used in AdvancedCache.filterEntries(..) gets 'null' as value param when traversing cache store entries ------------------------------------------------------------------------------------------------------------------------------ Key: ISPN-5697 URL: https://issues.jboss.org/browse/ISPN-5697 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 7.2.4.Final Reporter: Carsten Lohmann When using {{AdvancedCache.filterEntries(filter)}} on a cache with a cache loader (where not all entries are in memory), the {{accept(key, value, metadata)}} method of the given KeyValueFilter is invoked with {{null}} as value parameter for the cache loader entries. But the javadoc of {{filterEntries}} states: {quote} Callbacks to the filter will never provide a key or value that will be null. {quote} In the code: In the "{{if (shouldUseLoader(flags)}} \[..\]" block of {{LocalEntryRetriever#retrieveEntries}} the given filter is wrapped as a {{KeyValueFilterAsKeyFilter}} causing {{null}} to be used as value.
