             Summary: MulticastProcessor doProcessParallel blocks indefinitly 
if exception occurs in
                 Key: CAMEL-12441
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.21.0, 2.20.3, 2.20.2, 2.20.1, 2.20.0, 2.19.5
         Environment: Windows 8, java 1.8.0_162, camel 2.21.0
            Reporter: Bodor Maria Mihaela
             Fix For: 2.21.1

After upgrading from camel 2.17.5 to 2.21.0 the following problem was 

A camel RouteBuilder with a split :

public class MyRouteBuilder extends RouteBuilder {
    public void configure() throws Exception {
                      .xtokenize("//someTocken", 'i', NAMESPACES)
                      .aggregationStrategy(nw UseLatestAggregationStrategy())

Problem encountered:
A malformed xml arrives on this route. it.hasNext() returns true but 
throws an exception. This causes an indefinite wait in MulticastProcessor at 
line 374.

A call to countDown on aggregationOnTheFlyDone is never performed and thus the 
latch waits indefinitely.

Possible solution:
A call to aggregationOnTheFlyDone .countDown inside the catch corresponding to 
the try surrounding the while.
