----------------------------------------
Thanks - added additional details
> Unable to translate gremlin query to java
> -----------------------------------------
>
> Key: TINKERPOP-2649
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2649
> Project: TinkerPop
> Issue Type: Bug
> Components: translator
> Affects Versions: 3.5.1
> Reporter: Tom Kolanko
> Priority: Minor
>
> _updated description_
>
> In the user interface for Db2 Graph users enter Gremlin queries which get
> submitted as scripts. One feature that we are working on is helping users
> take their queries and use them in their own applications directly, instead
> of using our user interface to run queries. To achieve that we have a
> `translate query` button that shows them their query in the different
> language formats the translator supports. For the most part the Groovy
> translation just works in Java code, however, some data types are problematic.
>
> One unique aspect about Db2 Graph is that all your data is stored in Db2. Our
> implementation takes your Gremlin query and figures out the most optimized
> SQL statements to get the result set. We then execute the SQL statements and
> return the results. On occasion we may need to help Db2 understand how to
> translate a query, for example using java.sql.Timestamp.valueOf('2015-01-01
> 12:05:00') as a filter
>
> When this filter gets translated to Groovy it uses new
> Timestamp(1420113900000) which is invalid Java. We need to use new
> Timestamp(1420113900000L)
>
> I'm not sure if there would be other areas where the translated Groovy syntax
> does not work in Java, this is the only example I've foond
>
