It's not the class that's unsupported; it's the class file *version*. It
was created with a compiler more recent than your JVM.

48.0 corresponds to JDK 1.4, so you're trying to run with something older
than that.

After I updated my JDK or JVM, I was able to complete the install.
Now, I need SQL 101 guidance.
