Hi Frank,
I've just signed the contributor agreement (my username on bugs.python.org
is isaiah), thanks for pointing it out.
Because of the current immature status of the branch, I am trying to get as
much working as possible, so I didn't run the tests nor add new tests for
my work, hope that makes sense for the moment.
I also encountered a problem when trying to add the `int.from_bytes` class
method,
>>> int.from_bytes(b'\xfc\x00', byteorder='big', signed=True)
-1024
I tried to add
```java
@ExposedClassMethod(doc = BuiltinDocs.int_from_bytes_doc)
final static PyObject long_from_bytes(PyType type, PyObject[] args,
String[] keywords) {
...
}
```
But get the following exception when compiling:
*/home/isaiah/codes/java/jython3/build.xml:799:

It works with the following method, but it won't support keyword
parameters, and the `signed` argument cannot be optional:
```java
final static PyObject long_from_bytes(PyType type, PyObject bytes, PyObject
byteorder, PyObject signed) {
```
How to express such method signature in native implemented method?
Regards,
Isaiah
