Splitter Component: Setting 'streaming="true" parallelProcessing="true"'
consumes large amounts > of heap space for big original messages
-----------------------------------------------------------------------------------------------------------------------------------------
Key: CAMEL-3497
URL: https://issues.apache.org/jira/browse/CAMEL-3497
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.5.0
Reporter: Ralf Steppacher
Setting 'streaming="true" parallelProcessing="true"' consumes large amounts of
heap space for big original messages. E.g. 1024m of heap is not enough to
process an 80Mb with 500'000 lines, splitting it line by line.
The problem seems to be the ArrayList in MulticastProcessor line 224. It
contains a Future<Exchange> object for every token delivered by the
java.util.Scanner. The list is only cleared (going out of scope) after all
Future objects have been completed.
