[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-5121?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-5121.
-----------------------------------
    Fix Version/s: 8.12.x-6.4
       Resolution: Done


Changed the tuple source sharing logic to pass a new parameter to the request, which will direct the connector layer to create a copy of streaming lobs similar to when copyLobs is enabled.

> If a source returns streaming lobs and a shared tuple source is used, then a streaming exception can occur when the tuple source is reused.
> For example in TEIID-5093 a union of two identical branches of the same texttable will result in the exception: 
> TEIID60019 Streaming result has already been read once.
> This issue was separated from the S3 issue as it affects any streaming lob, which would typically be from the ws translator/resource adapter.
