Having the exact same issue with the exact same version of SCA and Java. I found this post as I was searching the error in quotes. I very much agree that this should not be marked as solved and is still an issue.
This thread was marked as Solved several years ago when it first occurred. Someone reawakened the thread for SCA 18.20, but the status remains.
There is another related post with more details for SCA 18.20 located here: https://community.softwaregrp.com/t5/Fortify-User-Discussions/Error-Access-Fortify-SCA-for-Python-amp-quot/td-p/1681548
