-------------------------------
Summary: Olingo Java v2 JPA processor concurrency problems while
building a query
Key: OLINGO-1277
URL: https://issues.apache.org/jira/browse/OLINGO-1277
Project: Olingo
Issue Type: Bug
Components: odata2-jpa
Affects Versions: V2 2.0.10
Reporter: Nikolay
Attachments: olingo.png
When querying simultaneously several filter queries similar to
{endpoint}/Logs/$count?$filter=(level%20eq%20%27ERROR%27)%20and%20(timeStamp%20ge%20datetime%272018-07-13T08:15:52%27%20and%20timeStamp%20le%20datetime%272018-07-13T09:15:52%27)
some of them fail due to concurrency problems - the query parameters get mixed
to different JPA queries:

If the oDataJPAContext in JPAProcessorImpl is volatile, the problem doesn't
occur any more.
