             Summary: JythonScriptEngineConfigurator needs to recompile on init()
                 Key: NIFI-8330
                 URL: https://issues.apache.org/jira/browse/NIFI-8330
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Matt Burgess


NIFI-8080 introduced a kind of regression in the sense that an invalid Jython script can be supplied to InvokeScriptedProcessor (or related scripting components) and it will successfully "compile". However it will generate an error every time eval() is called, and will not be recompiled if the script is changed because a CompiledScript object exists. The workaround/approach is that the script must be corrected and then NiFi must be restarted.

The JythonScriptEngineConfigurator should recompile the script whenever init() is called, whether there is an existing CompiledScript object or not.
