------------------------------------
Summary: NPE during concurrent express query cache invocation
Key: FINERACT-2756
URL: https://issues.apache.org/jira/browse/FINERACT-2756
Project: Apache Fineract
Issue Type: Improvement
Affects Versions: 1.15.0, 1.14.0, 1.13.0, 1.12.1, 1.10.1, 1.11.0
Reporter: Adam Saghy
Assignee: Adam Saghy
Fix For: 1.16.0
Issue
* The derived query causes intermittent EclipseLink-6168 errors (NPE and
ArrayIndexOutOfBoundsException during query preparation)
* This is a known EclipseLink thread-safety issue in ConcurrentFixedCache
([Intermittent NullPointerException in ConcurrentFixedCache.get [v2.6.7]
eclipse-ee4j/eclipselink#2374|https://github.com/eclipse-ee4j/eclipselink/issues/2374])
that affects derived query preparation under concurrent access
Fix:
* Replace Spring Data derived query with explicit @Query JPQL
* Using explicit JPQL bypasses the derived query preparation code path entirely
