Harold pointed out that removed logging flags (such as TraceClassInitialization) produce the following output now:

    Unrecognized VM option 'TraceClassInitialization'
    Error: Could not create the Java Virtual Machine.
    Error: A fatal exception has occurred. Program will exit.

We should add the following helpful error message:

    -XX:+TraceClassInitialization has been replaced by -Xlog:classinit=info
