[Jython-bugs] [issue2876] Null pointer exception PyModule.java

[Sunil <re...@bu...>]

New submission from Sunil <sun...@gm...>:

I am trying to integrate jython in my spring boot project. It is working for me in with Intellij but when I deploy jar for testing I keep getting null pointer exception from the library.

I am using java 8.

Exception:
java.lang.NullPointerException: null
at org.python.core.PyModule.module___init__(PyModule.java:64) ~[jython-standalone-2.7.2.jar!\/:2.7.2]

    public static JythonObjectFactory getInstance(){
        if(instance == null){
            instance = new JythonObjectFactory();
        }

        return instance;
    }

    public Object createObject(Object interfaceType, String moduleName){
        Object javaInt = null;
        PythonInterpreter interpreter = new PythonInterpreter();
        interpreter.exec("from " + moduleName + " import " + moduleName);

        pyObject = interpreter.get(moduleName);

        try {

            PyObject newObj = pyObject.__call__();

            javaInt = newObj.__tojava__(Class.forName(interfaceType.toString().substring(
                    interfaceType.toString().indexOf(" ")+1, interfaceType.toString().length())));
        } catch (ClassNotFoundException ex) {
            log.error(JythonObjectFactory.class.getName() + " error: " + ex.getMessage(), ex);
        }

        return javaInt;
    }
