---------------------------------------
Summary: Datasonnet expression fails on first runs in a route
called in multicast
Key: CAMEL-16918
URL: https://issues.apache.org/jira/browse/CAMEL-16918
Project: Camel
Issue Type: Bug
Components: camel-language
Affects Versions: 3.11.1
Reporter: Henrik Karlsson
I use a multicast().parallelProcessing() that calls three routes that all use
DataSonnet expressions. After starting the app the first runs of this route
fails with an java.util.ConcurrentModificationException.
I getting these two stack traces from to different threads:
Thread #1:

(!ds.isEmpty(cml.header('workplace_id'))) then ' and Id = :?workplace_id' else
'') else ''}}{{at
