sedatgoc / multiple-payload-downloader Goto Github PK

At work, I have 2 Java versions installed: JRE 8 and JDK 12. JDK 12 doesn't allow me to run this class because JavaFX is missing. On JRE 8, when downloading messages, I get this error:
error.log

The payload file gets created, but is of 0 size:

Program screen, before I hit the Download button, looks like this:

Below are my java versions:
java_versions.log

I tried different selection criteria, but none of the messages gets downloaded. Besides, where I expect multiple messages to be downloaded, empty file is created for the first of them only, while in the logs I can see as many exceptions as many payloads I expect.
