[jakartabatch-dev] BatchCDIInjectionExtension.foundJobOp field

[Cheng Fang <cfang@xxxxxxxxxx>]

I just noticed in JBatch BatchCDIInjectionExtension class, it contains a static foundJobOp to check if we need to create a built-in JobOperator producer:

https://github.com/WASdev/standards.jsr352.jbatch/blob/95cd0cf495c39426f4522747460b3b3a29e91068/com.ibm.jbatch.container/src/main/java/com/ibm/jbatch/container/cdi/BatchCDIInjectionExtension.java#L45

Should it be an instance variable (instead of a static one)? Image multiple batch apps are deployed to a server concurrently, some with application-defined JobOperator producer, and others don't, and they would interfere with each other.
