Empty .sa.tok files after select_functions & request to release self_training dataset

I am trying to create the self-training dataset, as per the instructions at https://github.com/facebookresearch/CodeGen/blob/main/docs/TransCoder-ST.md.

From Google BigQuery, I got 500 `.json.gz` files. Thereafter I preprocessed them and got the following symlinks successfully:

```
[abc@def CodeGen]$ ls xyz/java-FULL/XLM-syml/
test.java_cl.pth train.java_cl.0.pth train.java_cl.2.pth train.java_sa.1.pth valid.java_cl.pth
test.java_sa.pth train.java_cl.1.pth train.java_sa.0.pth train.java_sa.2.pth valid.java_sa.pth
[abc@def CodeGen]$
```

But now, as part of the final step, I am facing an issue on running `create_self_training_dataset.sh`. As per the following output that I am getting, all the `.sa.tok` files in the selected_functions folder are empty.

On debugging, I found that `is_simple_standalone_func(func)` in line 67 of at [Link](https://github.com/facebookresearch/CodeGen/blob/6e93aca63e7bc77287c9965a5080456326651237/codegen_sources/test_generation/select_java_inputs.py#L67) is returning `False` for all the Java functions. As such, the mask in line 114 in `select_functions(funcpath)` is an all-False list. Please suggest what to do in this case.

Also, it would be great if the authors can please release the training dataset of 135,000 parallel functions (as mentioned in the [paper](https://arxiv.org/pdf/2110.06773.pdf)) between Java, Python, and C++, in the form of a shareable link.
