/**
 * To pass command line arguments to a JUnit test, set the system property "max.test.arguments" on the VM command line or
 * where ever VM arguments are specified in the IDE. Multiple command line arguments must be separated with a space or
 * a colon. For example, to pass these arguments to a JUnit test:
 * <p><pre>
 *     -vmclasses
 *     -jcklist=test/test/com/sun/max/vm/verifier/jck.classes.txt
 * </pre><p>
 * requires defining the system property on the VM command line as follows:
 * <p><pre>
 *     -Dmax.test.arguments=-vmclasses -jcklist=test/test/com/sun/max/vm/verifier/jck.classes.txt
 * </pre><p>
 * or:
 * <p><pre>
 *     -Dmax.test.arguments=-vmclasses:-jcklist=test/test/com/sun/max/vm/verifier/jck.classes.txt
 * </pre><p>
 * If using the latter (colon-separated) form, then colons in an argument must be escaped with a backslash.
