> camel-djl: the loaded ZooModel is never closed (native-memory leak on restart)

> Key: CAMEL-24529
> URL: https://issues.apache.org/jira/browse/CAMEL-24529
> Project: Camel
> Issue Type: Bug
> Components: camel-ai
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Major
> Fix For: 4.23.0

>
> DJL zoo predictors load a ZooModel (ModelZoo.loadModel) in their constructor,
> but DJLProducer has no doStop() and AbstractPredictor has no close(), so the
> native ZooModel (NDManager/engine memory) is never released on route
> stop/redeploy or CamelContext restart — a native-memory leak. The huggingface
> sibling cleans up (AbstractTaskPredictor.close via
> HuggingFaceProducer.doStop). The per-exchange Predictor objects are correctly
> try-with-resources; only the model is leaked.
> Fix: add close() to AbstractPredictor (closing the model), keep the predictor
> reference in DJLProducer, and override DJLProducer.doStop() to close it.
