"java.lang.IllegalArgumentException: Illegal Capacity: -2147483647

Whenever I call simulate_measurements() function with a config as a dict, I get the following error message from the java server:

In [31]: print(si.simulate_measurements(config, output_file="output.json"))

I get this error even when I use the config files in example/data directory.

This does not happens when config is a file path.
I'm working from a virtualenv with python 3.7.2, from a debian9 machine with the following java version:

$ java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1~deb9u1-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

orbdetpy no longer uses the JSON export/import semantics starting with v2.0.0. It now uses a more declarative function call model for passing parameters. Closing this issue because there is no plan to bug fix old releases.
