ChainedInstrumentation not finishing #1110
Description
Upgrading from 7.0 to 9.0.
I've been using a ChainedInstrumentation that chains MaxQueryComplexityInstrumentation, DataLoaderDispatcherInstrumentation and TracingInstrumentation. This worked well in 7.0.
Now, having updated the dependencies to 9.0 for graphql-java, 5.0.1 for graphql-servlet and 4.2.0 for graphql-spring-boot, a query that has to invoke more than one resolver sequentially, does not return.
I've narrowed it down to the following Instrumentation not working:
return new ChainedInstrumentation(Arrays.asList(new DataLoaderDispatcherInstrumentation(...)))
And the following does work:
return new DataLoaderDispatcherInstrumentation(...)
The queries that fail are hierarchical with resolvers, so for instance:
{ entity(id=1) { property } },
will work if the property is fetched by a resolver without a batchloader, but will fail if the resolver for property also uses a batchloader (it simply does not get invoked/triggered).
Any pointers or things I can try?
