Review comment:
Perhaps a little bit more elegant:
```java
public default TraversalSource with(final String key, final Object
value) {
final OptionsStrategy.Builder builder = OptionsStrategy.build();
getStrategies().getStrategy(OptionsStrategy.class)
.ifPresent(optionsStrategy ->
optionsStrategy.getOptions().forEach(builder::with));
builder.with(key, value);
return withStrategies(builder.create());
}
```

-
However, the fix also went into the release branches for the versions 3.2.10
and 3.3.4 which we expect to release relatively soon. So, you can just wait for
the release of 3.3.4 and then use that version.
Anyway, thanks for reporting back on this. I guess we can now close this
ticket. You can re-open or comment here again in case you see this problem
again with 3.4.0-rc2 or the to be released version 3.3.4.

We've upgraded to 3.4.0-rc2. That branch seems to have solved the issue because
we no longer get those exceptions, Florian.
We're about to release end of October. How soon would 3.4 be ready for
production?

We've delayed a full 3.4.0 for a couple of months. I don't think we'll release
it until the end of the year.

Should we attempt to fix the problem at its source - in other words fix the
{{union()}} signature?

We've upgraded to 3.4.0-rc2 and it seemed to have solved the problem. We're
about to release in the next two weeks. Would 3.4 be production ready soon?

[jira] [Created] (TINKERPOP-2062) Add Traversal class to CoreImports

Summary: Add Traversal class to CoreImports
Key: TINKERPOP-2062
URL: https://issues.apache.org/jira/browse/TINKERPOP-2062
Project: TinkerPop
Issue Type: Improvement
Components: server
Affects Versions: 3.3.3
Reporter: Daniel Kuppitz
Assignee: Daniel Kuppitz
Apparently, some people like to copy Gremlin queries they've written in Java
and paste them into the Gremlin console. This should usually work pretty well,
however, there are some oddities in particular with {{union()}} step which
requires you to cast the child traversals to {{Traversal}} if they have
different return types, e.g.:
{noformat}
g.V().
union(
__.identity(),
(Traversal)__.outE()
)
{noformat}
This works in a local console session but fails if the query is sent to a
server as {{Traversal}} is not part of the core imports.

AW: [DISCUSS] Add Gremlin IDE to Provider Index
Big +1 from my side and thanks for your work on this tool, Dave! A tool to visualize the results of Gremlin traversals is the most important thing that was missing (apart from GremlinBin which seems to be offline) in the TinkerPop ecosystem from my point of view. -Ursprüngliche Nachricht- Von: Stephen Mallette Gesendet: Donnerstag, 11. Oktober 2018 13:53 An: dev@tinkerpop.apache.org Betreff: [DISCUSS] Add Gremlin IDE to Provider Index Gremlin IDe has announced a new release. I was a bit surprised that we didn't have it in the Powered By section yet: https://github.com/bechbd/gremlin-ide Unless there are objections in the next 72 hours, I will assume lazy consensus and move forward to get this added.
