Claus Ibsen resolved CAMEL-15366.
---------------------------------
Resolution: Information Provided
> Parallel processing a poll enrich throws a RejectedExecutionException
> ---------------------------------------------------------------------

> Key: CAMEL-15366
> URL: https://issues.apache.org/jira/browse/CAMEL-15366
> Project: Camel
> Issue Type: Bug
> Components: camel-core-engine
> Affects Versions: 3.3.0
> Environment: Spring Boot 2.3.0.RELEASE
> Apache Camel 3.3.0
> Reporter: Alessio Villa
> Priority: Major
>
> The following route receives a message containing a collection of objects
> representing files (path/name); it then splits the body and, for each
> element, reads the corresponding file (through a pollEnrich) and writes it to
> a different directory:
> from("direct:copy")
> .split(body()).streaming().parallelProcessing()
>
> .pollEnrich().simple(format("file://${body.path}?fileName=RAW(${body.name})&noop=true&idempotent=false").timeout(0).end()
> .to("file:target")
> .end();
>
> The source directory contains 2000 test files (txt, 1KB each) and, after
> around 1350-1550 files, the test fails by throwing the following exception(s):
