dumpZipPrefix

public static java.lang.String dumpZipPrefix

Used to control which .zip file dumps are generated.

interactiveCounter

public static int interactiveCounter

Numeric identifier for this interactive "command". Incremented by Shell.run, and used to set the module name, and maybe the name of the --debug-dump-zip output file. We increment and use this counter purely to ease debugging. (Since each module gets its own ClassLoader, they don't need to be named differently, and it doesn't matter if there is a race condition on the counter.)

alwaysCompile

public static boolean alwaysCompile

Flag to force compilation, even when not required.
