F-Secure finds 3 instances of Java/Blackhole malware exploit in Processing docs zip file

Issue description

Steps to reproduce: (28 November 2020)
OS Windows 10 Pro, latest version;
Microsoft Edge, latest version.
F-Secure anti-virus, fully up-to-date:

Downloaded zip file of processing/docs (28 November 2020).
Scanned with up-to-date F-Secure anti-virus.
3 instances of the blackhole exploit found:

[2] BApplet.class
Exploit.EXP/Blacole.S.9

Category: Malware
Type: Exploit
Platform: Java

3 specific harmful items found (from the F-Secure report):

Exploit.EXP/Blacole.S.9
processing-docs-master.zip[5754] processing-docs-master/exhibition/works/cdrawer/cdrawer.jar[2] BApplet.class
processing-docs-master.zip[5909] processing-docs-master/exhibition/works/inequality/inequality.jar[2] BApplet.class

F-Secure reported that it was unable to clean the files. I reverted to deleting the zip file.

Proposed fix

Author to examine original code files, perhaps send individual files to F-Secure for analysis; remove exploit from affected files if the exploit is real, or modify the code to prevent false negative if that's the case, or post notice that such a false negative exists and can be safely ignored.

I would have sent the zip file to F-Secure for analysis myself, but their file-size limit is 30Mb. I'm not opening the zip file myself just in case this is a real issue.

Start with the three reported paths in the docs archive: exhibition/works/cdrawer/cdrawer.jar, inequality/inequality.jar, and sodaprocessing/sodaprocessing.jar, focusing on each BApplet.class. Compare these files with their original code and submit individual files to F-Secure for analysis if possible. Done means confirming whether the detections are real or false positives, then removing the exploit or documenting a safe false-positive response.
