Issue1745

Error happens when calling PythonInterpreter from Java.
Example Java code:

    interp = new PythonInterpreter();
    interp.put("arr", new double[3]);
    interp.exec("arr.append(3.0)\n\n");
    o = interp.get(arr, Object.class);

o ends up as double[7] with 3.0 in position 3.
Should be double[4].

Error is in PyArray.__toJava__(Class)
where it returns 'data' instead of calling this.getArray() which calls delegate.copyArray().

I added a test (https://hg.python.org/jython/rev/837c14575b65) based on what Judah submitted here:

    public void testCompactArray() {
	// tests http://bugs.jython.org/issue1745
	PythonInterpreter interp = new PythonInterpreter();
	interp.put("arr", new double[3]);
	interp.exec("arr.append(3.0)\n\n");
	o = interp.get(arr, Object.class);
    }

and determined this problem must have been fixed a while ago - it was not changed by the recent work in https://hg.python.org/jython/rev/49d498968f34
