superclass methods not accessible in 1.2.1

arraylist = autoclass("java.util.ArrayList")()
arraylist.iterator()
arraylist.stream()

This works for 1.2.0 but not for 1.2.1.

Reproducible notebook at https://colab.research.google.com/drive/1F9u2jVQR5JFw_mk5Bq--VH1Ki91Xe5x3

stream() is defined in the super-interface as a default.

We also had problem accessing methods in interfaces that extended java.util.List.

I observe the same problem, superclass methods are not accessible in 1.2.1 but everything works in 1.2.0. This is quite nasty bug, don’t you think it make sense to remove 1.2.1 release or somehow mark it as unusable ?

I had wondered if this was a concurrency issue as per #480, but I don’t think pytest is concurrent by default.

I tried reproducing locally, but didn’t succeed in reproducing #480. Here was my command - its a Debian-based image:

docker run -i continuumio/anaconda3 /bin/bash <<EOF

cat /etc/os-release
apt-get update
mkdir /usr/share/man/man1
apt-get -y install openjdk-11-jdk-headless gcc ant

conda create -y -n pyjnius python=3.7.5
conda activate pyjnius

git clone https://github.com/kivy/pyjnius.git
cd pyjnius/
python -m pip install -U setuptools cython
python setup.py bdist_wheel
pip install --timeout=120 .[dev,ci]
