-------------------------------------
Summary: Stack size increases in split with transacted
Key: CAMEL-16103
URL: https://issues.apache.org/jira/browse/CAMEL-16103
Project: Camel
Issue Type: Bug
Components: camel-core, camel-spring
Affects Versions: 3.7.1, 3.6.0
Environment: OS: Windows 10
Java: OpenJDK jdk-8.0.282.8-hotspot
Camel: 3.6.0 and 3.7.1
I'm using camel-spring and Spring version is 5.1.5.RELEASE
Reporter: Stefano Rocca
Hi,
I have run into an anomalous stack usage with this simple route:
<route id="split-stack-test" autoStartup="true">
<from uri="quartz://split-stack-test?cron=0+16+15+?+*+*"/>
<transacted/>
<setBody><groovy>(0..499).collect { it }</groovy></setBody>
<split>
<simple>${body}</simple>
<setBody><groovy>"${body}
${Thread.currentThread().getStackTrace().size()}"</groovy></setBody>
<log message="STACKTRACE *** ${body}"/>
</split>
<to uri="mock:done?retainLast=0"/>
</route>
As you can see it prints the iteration number and the stack size (limited to
1024) and the output I get at the end is
STACKTRACE *** 499 1024
(The size of the stack reaches 1024 at 117)
The stack is filled with these calls:

If I remove transacted, the stack size remains at 15.
