probably not too well the most important metrics it uses to determine if your code is bug prone according to their tech paper are: # of comments, file size, javadoc usage, and using { } after if statements. These kind of metrics probably do statistically correlate to correct and incorrect programs. Careful programmers often use javadoc and heavy commenting. However, just because you don't use comments doesn't mean your code is incorrect. And programmers already know if they use javadoc and comments, they don't need a tool to tell them.
