Summary: Developer warning when HashMap is passed to putAll() Key: IGNITE-11558 URL: https://issues.apache.org/jira/browse/IGNITE-11558 Project: Ignite Issue Type: Improvement Components: cache Affects Versions: 2.7 Reporter: Ilya Kasnacheev Currently when HashMap is passed to putAll it's very easy to cause deadlock since the order of keys is not stable. This is a pity because users will use HashMap by default and not expect any trouble. We should issue a warning when user passes HashMap (but not LinkedHashMap) to putAll(). On .Net we should probably check for Dictionary. Warning similar to the one issues when index cannot be efficiently inlined. Another approach is to turn keys into binary form and then sort them, if map is not a SortedMap. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
