Project tree still broken by bad JSP code in 3341 :(

I do get a new exception, but the project tree still fails to show up on
startup if I have my project's web folder expanded during the previous close.
Below is the exception. It seems to be a different file causing the problem,
though -- wasn't the text of the file supposed to be displayed when parsing
errors preventing the project tree from drawing?
