`LiteralReplacement`-Cache is not threadsafe.

[ajanoni]

It is a random error that occurs in different queries in our application:

Here is the stack trace:

2021-09-08 08:53:41	at org.springframework.data.neo4j.repository.query.Neo4jSpelSupport.orderBy(Neo4jSpelSupport.java:71)

Could you please provide any further information?

• Query you used. I assume that this is a @Query annotated repository method.
• Spring Data Neo4j version
• If applicable custom versions of the Java driver and similar.

The best would be to get a small reproducer for the problem you are facing.

The error does occur in other queries that have the orderBy clause, but you can check one example bellow:

Query:

import org.springframework.data.domain.Pageable
import org.springframework.data.domain.Slice
import org.springframework.data.neo4j.repository.Neo4jRepository
import org.springframework.data.neo4j.repository.query.Query

interface AcmeGroupsRepository : Neo4jRepository<AcmeGroupEntity, String> {
    companion object {
        const val BASE_QUERY =
            """
        MATCH (acmeGroup:AcmeGroup)
        WHERE 
          ($${"ids"} IS NULL OR acmeGroup.id IN $${"ids"}) AND  
          ($${"labels"} IS NULL OR acmeGroup.label IN $${"labels"})
        """
    }

    @Query(
        """
        $BASE_QUERY
        RETURN acmeGroup :#{orderBy(#pageable)} SKIP $${"skip"} LIMIT $${"limit"}
    """
    )
    fun findAllByFilters(ids: List<String>?, labels: List<String>?, page: Pageable): Slice<AcmeGroupEntity>

Version: org.springframework.data:spring-data-neo4j:6.1.4
