-----------------------------------
Summary: JythonScriptEngineConfigurator fails to account for
Python escaping in Module Directory property
Key: NIFI-6186
URL: https://issues.apache.org/jira/browse/NIFI-6186
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.9.1, 1.9.0, 1.7.1, 1.8.0, 1.7.0, 1.6.0, 1.5.0, 0.7.4,
1.4.0, 1.3.0, 1.0.1, 1.1.1, 1.2.0, 0.7.1, 1.1.0, 0.6.1, 0.7.0, 0.5.1, 0.6.0,
0.5.0, 1.0.0, 0.8.0, 1.9.2
Reporter: Andrew Mathis
Currently, JythonScriptEngineConfigurator (in its init() method) incorporates
the module directory list (as derived from the Module Directory property value)
into evaluated Jython code as string literals without any regard to how the
paths will be interpreted in Jython. This means that Module Directory paths
that include Jython escape sequences (e.g. "\a", "\1") will be mis-interpreted
in Jython execution. Rather than interpreting paths directly as Python string
literals, a method like PyString.encode_UnicodeEscape should be used to
translate the Java strings into appropriate Jython string literals.
This issue will be especially relevant in Windows, where paths will often
contain backslashes.
