Error while parsing JAI registry file

Hello everyone. I’m running esa_snappy on Python after the update of SNAP 10, and I’m trying by only reading a file. Here’s the code snippet:
import esa_snappy
from esa_snappy import ProductIO, Product

path = “path_to_my_file”
ProductIO.readProduct(path)

The operation is effectuated correctly, but before the execution I have this message

What does it mean? How to solve it?
