Randoop fails with a runtime exception when generating tests for spring

[jensdietrich]

In my setup I try to generate tests for spring beans using the following parameters:

--testjar <some-path>/spring-beans-5.3.22.jar --no-regression-assertions --junit-package-name=generated.org.springframework.beans --junit-output-dir=generated-tests --log=randoop-spring-beans-5.3.22.log

The classpath work, and I have generated tests for some particular classes successfully. However, when I try to run this on the jar, randoop fails with an IllegalStateException caused by a failed spring assertion.

I have also notices this exception that always seemed to happen just before:

Will try to generate tests for 286 classes.
Removing org.springframework.beans.factory.groovy.GroovyDynamicElementReader$_invokeMethod_closure1 from the classes under test due to problem extracting operations:
