That ship has already sailed. Somebody has decompiled the Java programmer, found the f/w AES encryption keys, downloaded his own snooper app to the chip and extracted the bootloader, patched it to not burn the read-lock bits... and there are already ...
I'm getting this problem too, on a clean Win 10 1909, having just installed the s/w and ST-Link V2 but no hardware (all boxed up to go back to work).OS is 64-bit but Java is 1.8.0_25 32-bit.
