-------------------------------------
Summary: Java 11 - Druid Query to Rel node error
Key: CALCITE-4502
URL: https://issues.apache.org/jira/browse/CALCITE-4502
Project: Calcite
Issue Type: Bug
Components: druid-adapter
Reporter: Rajat Mittal
I am using calcite to convert druid query to SQL. Here is the open-source code
for the web service that I use:
[https://github.com/yahoo/fili/blob/master/fili-sql/src/main/java/com/yahoo/bard/webservice/sql/DruidQueryToSqlConverter.java#L423-L452]
When I upgrade to using Java 11 for this code, it is able to compile but gives
me a runtime error.
{code:java}
17:42:56.740 ERROR [ForkJoinPool.commonPool-worker-3]
c.y.b.w.w.r.MappingResponseProcessor - Failed to send the query
com.yahoo.bard.webservice.druid.model.query.TopNQuery@3a615251 to Druid.

{code}
Nothing in my code has changed apart from building the source code using Jdk11
instead of Jdk8. The web service is also capable of serving endpoints that do
not use calcite and they all run fine. Any help here would be appreciated.
