Which plugin (installed on wordpress.com) allows code snippets

I used wordpress.com for my blog, but moved it to my own server recently. However, I used the following syntax:

[code language="Java"]
...
[/code]

to style my code snippets, and this is now not happening in the new blog. So which exactly is the plugin that does this? I tried a few, but they don’t handle exactly this syntax, and I don’t want to edit all my posts.
