I need some help with a Camel issue.
To summarise my issue, we have upgraded from Camel 2.16.2 to 3.7.3 and in our
route xml the <split> no longer works.
The object (xx.ObjectListDto) we are trying to split looks like this --->
private static final long serialVersionUID = 2947839802965876099L;
@NotNull
@Valid
@Size(min = 1)
private List<T> scheduledServices;
public List<T> getScheduledServices()
{
return this.scheduledServices;
}
public void setScheduledServices(final List<T> scheduledServices)
{
this.scheduledServices = scheduledServices;
}
and the route looks like this --->
<policy ref="transactedRequiredMast">
<split stopOnException="true" parallelProcessing="true">
<simple>${body?.scheduledServices}</simple>
<to uri="bean:aBean?method=aMethod(${header.assetId}, ${body.id})"/>
<to uri="bean:bBean?method=bMethod(${header.assetId}, ${body}, true)"/>
</split>
</policy>
The stacktrace looks like this ---->
the [xx.ObjectDO] entity was modified, but it won't be updated because the
property is immutable.

It seems the splitter can no longer pull the list out of the body object
(xx.ObjectListDto). And thus the method (id) on the list object, which is
expected to be in body but isn't, is unrecognised. Note also that although the
body is not being set correctly by <split>, it does recognise that there are 2
elements in the list and thus attempts to process body.id twice. Very strange.
Note that in our splitter, we have tried:
body?.scheduledServices
body.scheduledServices
body.getScheduledServices
none of which work.
In our previous system config, the split did work.
Previous config
hibernate 5.0.3
Spring-data 1.9.2.RELEASE
Javassist 3.19.0-GA
Camel 2.16.2
Spring 4.2.2.RELEASE
Jackson 2.6.5
Spring-security - N/A
Current config
hibernate 5.4.28
Spring-data 2.3.7.RELEASE
Javassist 3.27.0-GA
Camel 3.7.3
Spring 5.2.13.RELEASE
Jackson 2.12.3
Spring-security - 5.4.5
Any asisstance on this would be hugely appreciated.
Doug Snaith.
