[jira] [Commented] (TINKERPOP-1574) Get rid of untyped GraphSON 2.0

["Daniel Kuppitz (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP-1574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15735408#comment-15735408 ] 

Daniel Kuppitz commented on TINKERPOP-1574:
-------------------------------------------

A specific problem popped up recently: I was using {{constant(Collections.emptySet())}} in a traversal which was causing errors, because the serialized {{Set}} was deserialized as a {{List}} (for untyped GraphSON all implementations of {{Collection}} look the same and thus every {{Collection}} is considered to be a {{List}}). A workaround has been added in this commit: https://github.com/apache/tinkerpop/commit/69b314cb2e52f33dbab29d3cddaadacb4ec69099
I think, once the GraphSON issue is fixed, the workaround should be reverted as it seems to be a good extra test case.

> We should not have GraphSON 2.0 untyped. Too many degrees of freedom. GraphSON should be GraphSON typed and thats that.
