WP-Markdown treating java generics like HTML tags

I just had a very frustrating experience with the WP Markdown plugin.

With some Java generic code in a code block, ie:

List<Integer> l = new ArrayList<Integer>();

WP-Markdown was treating <Integer> as HTML, and no matter what I did, the code above got turned into something like

List<Integer> l = new ArrayList</Integer><Integer>();</Integer>

Is there any way to get WP Markdown to behave better with this kind of code? Gist and Stackoverflow don’t have this problem.
