Radu Cotescu updated SLING-11458:
---------------------------------
Fix Version/s: (was: GraphQL Core 0.0.6)
> Regress - "Writer has already been closed" exception in GraphQLServlet
> ----------------------------------------------------------------------
>
> Key: SLING-11458
> URL: https://issues.apache.org/jira/browse/SLING-11458
> Project: Sling
> Issue Type: Bug
> Components: GraphQL
> Affects Versions: GraphQL Core 0.0.4
> Reporter: Evgeny Tugarev
> Assignee: Andreas Schaefer
> Priority: Major
>
> The GraphQLServlet shouldn't call {{response.getWriter().flush()}} as the
> {{JsonWriter}} used by the {{JsonSerializer}} implements {{Closeable}} and as
> such [closes the
> Writer|https://github.com/jdereg/json-io/blob/cf849f15460decf10a8a320390de11965bb5996b/src/main/java/com/cedarsoftware/util/io/JsonWriter.java#L2413].
> This causes a "Writer has already been closed" Exception when {{flush()}} is
> called.
> This was fixed in commit d27f4bb7 but then this commit: 11c7e389 did undo the
> fix as now the JsonWriter is closed when existing the try-catch block.
> I will undo it and prevent the premature closure as this is causing issues
> like when the call to this servlet is made through a dispatcher.
