This issue is due to the following:
JMeterThread#process_sampler calls :
SamplePackage pack = compiler.configureSampler(current);
This calls :
configureWithConfigElements(sampler, pack.getConfigs());
Which ends up calling:
mergeIn()
This methods iterates over HeaderManager properties and adds them to
AbstractTestElement as temporary properties but it adds their reference not a
clone.
So AbstractTestElement ends up sharing a CollectionProperty with HeaderManager
When sampler.recoverRunningVersion() is called in
SamplePackage#recoverRunningVersion(), it calls prop.recoverRunningVersion(this
being AbstractTestElement)
This calls recoverRunningVersionOfSubElements(this being AbstractTestElement)
This enters this part of code:
if (owner.isTemporary(prop)) {
iter.remove();
}
And ends up cleaning HeaderManager collection.
So I think the issue is due to the fact that A CollectionProperty is shared
between HeaderManager and AbstractTestElement.
You can see this behaviour by just disabling the 2 HTTP Samplers and keeping
only the BeanShellSampler or any other AbstractTestElement except for those who
redefined addTestElement (as it's the case for HttpSamplerBase).
I attach a patch (not committed) because I need further advice from Sebb
regarding the fix and its impacts.
