Ok, I'm with it now I think, the two factors are the use of flush() (I'm not using that anywhere) and the buffer size, I probably exceed the buffer before the exception occurred.
You did call me out on my poor best practices, I do have too much unchecked code in my JSP, so thanks for pointing that one out, I'll improve those practices. Thanks Chris and Charles for pointing me in the right direction!

Usually when this kind of thing happens, it's because someone is packing way too much logic into a JSP that really should be a servlet-then-JSP model. >> Is there a way to ensure the exception page is displayed on >> exceptions (or in the future to ensure that the defined pretty error >> page is displayed)? > > Fix your webapp to not send partial responses.
