[OLINGO-1277] Olingo Java v2 JPA processor concurrency problems while building a query

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: V2 2.0.10

Description

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:

org.hibernate.QueryException: Named parameter [1] not set

at org.apache.olingo.odata2.jpa.processor.core.access.data.JPAProcessorImpl.process(JPAProcessorImpl.java:232)

 

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