             Summary: Queries that invoke StructSet addAll fail with ClassCastException
                 Key: GEODE-2124
                 URL: https://issues.apache.org/jira/browse/GEODE-2124
             Project: Geode
          Issue Type: Bug
            Reporter: Barry Oglesby


A query like this fails with the exception below:
{noformat}
select distinct oP.ID, oP.status, oP.getType from /data oP where element(select distinct p.ID, p.status, p.getType from /data p where p.ID = oP.ID).status = 'inactive'
{noformat}
{noformat}

The Collection being passed into the addAll method are the same in Geode and GemFire 8.x:

Geode:
{noformat}
c=[struct(ID:648,status:inactive,getType:type1)]; class=class java.util.HashSet
  o=struct(ID:648,status:inactive,getType:type1); class=class org.apache.geode.cache.query.internal.StructImpl
{noformat}
GemFire 8x:
{noformat}
c=[struct(ID:562,status:inactive,getType:type1)]; class=class java.util.HashSet
  o=struct(ID:562,status:inactive,getType:type1); class=class com.gemstone.gemfire.cache.query.internal.StructImpl
