I've run into an issue in Camel 4.14 when using the Split EIP using parallel
processing and a shared unit of work. On top of that, I have JMX enabled,
and that's when the issue surfaces.
I drafted a simple route to reproduce the issue
{code:java}
from("direct:start")
.setBody(constant(Stream.iterate(1, i -> i + 1).limit(1000).toList()))
.split().body()
.shareUnitOfWork()
.parallelProcessing()
.log(LoggingLevel.INFO, log, "Number ${body}")
.end()
.log(LoggingLevel.INFO, log, "All done");
{code}
I've attached an MRE as well as the resulting exception stacktrace.
