Java problem

There is a small problem I’m having with this plugin. I use this to display Java code.
These are the tags I use in my posts:

<pre name="code" lang="java">
</pre>

Everything works fine and looks really nice except for one thing. < is changed into <. Since I use code that uses the < and > this is a pretty big problem. Did I do something wrong or is this a problem with the plugin?
