Bug in VASSAL 3.19 (and others)

Technical Support & Bugs
1

After downloading VASSAL 3.19, the program reports a bug instead of starting. The same has happened when I downloaded 3.17 and 3.15. Not only that, but when I then log out of Windows, the system won’t re-start.

Thus spake dpafine:

An UnsatisfiedLinkError for a Java method is always a prblem with Java,
not VASSAL. Either you’ve hit a Java bug or you have a bad install. Try
reinstalling Java. Does that resolve the problem?

That was the trick. Re-loading Java also seems to have speeded up downloads generally, which has been a big problem for me. Thanks very much!
