Description

NIFI-7447 added a test `TestStandardControllerServiceInvocationHandler` that resets the class loader. This causes `TemplateDeserializerTest` and `TemplateSerializerTest` in nifi-framework-core to fail with "javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath" and "java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory" with Java 11 depending on whether they run before or after `TestStandardControllerServiceInvocationHandler`.

I've observed it on two machines, one Mac and one Linux, and across different builds and versions of OpenJDK.

Compare:

mvn test -ff -Dsurefire.runOrder=alphabetical -Dtest="org.apache.nifi.persistence.TemplateDeserializerTest,org.apache.nifi.controller.service.TestStandardControllerServiceInvocationHandler"

To:

mvn test -ff -Dsurefire.runOrder=reversealphabetical -Dtest="org.apache.nifi.persistence.TemplateDeserializerTest,org.apache.nifi.controller.service.TestStandardControllerServiceInvocationHandler"

And:

mvn test -ff -Dtest="!*IT,!org.apache.nifi.controller.service.TestStandardControllerServiceInvocationHandler"

The first fails and the second two succeed.
