Exactly. To be "fully compatible" with RI, we may support the following syntax:
 - options are set with -XX:<option>=<string>
 - Boolean options are turned on with -XX:+<option> and turned off
with -XX:-<option>
 - Numeric options are set with -XX:<option>=<number>. Numbers can
include 'm' or 'M' for megabytes, 'k' or 'K' for kilobytes, and 'g' or
'G' for gigabytes (for example, 32k is the same as 32768).
